# Community Integrations Guide
Pipecat welcomes community-maintained integrations! As our ecosystem grows, we've established a process for any developer to create and maintain their own service integrations while ensuring discoverability for the Pipecat community.
## Overview
**What we support:** Community-maintained integrations that live in separate repositories and are maintained by their authors.
**What we don't do:** The Pipecat team does not code review, test, or maintain community integrations. We provide guidance and list approved integrations for discoverability.
**Why this approach:** This allows the community to move quickly while keeping the Pipecat core team focused on maintaining the framework itself.
## Submitting your Integration
To be listed as an official community integration, follow these steps:

## Integration Patterns and Examples
### STT (Speech-to-Text) Services
#### Websocket-based Services
**Base class:** `STTService`
**Examples:**
- [DeepgramSTTService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/deepgram/stt.py)
- [SpeechmaticsSTTService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/speechmatics/stt.py)
#### File-based Services
**Base class:** `SegmentedSTTService`
**Examples:**
- [RivaSTTService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/riva/stt.py)
- [FalSTTService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/fal/stt.py)
#### Key requirements:
- STT services should push `InterimTranscriptionFrames` and `TranscriptionFrames`
- If confidence values are available, filter for values >50% confidence
### LLM (Large Language Model) Services
#### OpenAI-Compatible Services
**Base class:** `OpenAILLMService`
**Examples:**
- [AzureLLMService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/azure/llm.py)
- [GrokLLMService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/grok/llm.py) - Shows overriding the base class where needed
#### Non-OpenAI Compatible Services
**Requires:** Full implementation
**Examples:**
- [AnthropicLLMService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/anthropic/llm.py)
- [GoogleLLMService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/google/llm.py)
#### Key requirements:
- **Frame sequence:** Output must follow this frame sequence pattern:
- `LLMFullResponseStartFrame` - Signals the start of an LLM response
- `LLMTextFrame` - Contains LLM content, typically streamed as tokens
- `LLMFullResponseEndFrame` - Signals the end of an LLM response
- **Context aggregation:** Implement context aggregation to collect user and assistant content:
- Aggregators come in pairs with a `user()` instance and `assistant()` instance
- Context must adhere to the `LLMContext` universal format
- Aggregators should handle adding messages, function calls, and images to the context
### TTS (Text-to-Speech) Services
#### AudioContextWordTTSService
**Use for:** Websocket-based services supporting word/timestamp alignment
**Example:**
- [CartesiaTTSService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/cartesia/tts.py)
#### InterruptibleTTSService
**Use for:** Websocket-based services without word/timestamp alignment, requiring disconnection on interruption
**Example:**
- [SarvamTTSService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/sarvam/tts.py)
#### WordTTSService
**Use for:** HTTP-based services supporting word/timestamp alignment
**Example:**
- [ElevenLabsHttpTTSService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/elevenlabs/tts.py)
#### TTSService
**Use for:** HTTP-based services without word/timestamp alignment
**Example:**
- [GoogleHttpTTSService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/google/tts.py)
#### Key requirements:
- For websocket services, use asyncio WebSocket implementation (required for v13+ support)
- Handle idle service timeouts with keepalives
- TTSServices push both audio (`TTSRawAudioFrame`) and text (`TTSTextFrame`) frames
### Telephony Serializers
Pipecat supports telephony provider integration using websocket connections to exchange MediaStreams. These services use a FrameSerializer to serialize and deserialize inputs from the FastAPIWebsocketTransport.
**Examples:**
- [Twilio](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/serializers/twilio.py)
- [Telnyx](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/serializers/telnyx.py)
#### Key requirements:
- Include hang-up functionality using the provider's native API, ideally using `aiohttp`
- Support DTMF (dual-tone multi-frequency) events if the provider supports them:
- Deserialize DTMF events from the provider's protocol to `InputDTMFFrame`
- Use `KeypadEntry` enum for valid keypad entries (0-9, \*, #, A-D)
- Handle invalid DTMF digits gracefully by returning `None`
### Image Generation Services
**Base class:** `ImageGenService`
**Examples:**
- [FalImageGenService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/fal/image.py)
- [GoogleImageGenService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/google/image.py)
#### Key requirements:
- Must implement `run_image_gen` method returning an `AsyncGenerator`
### Vision Services
Vision services process images and provide analysis such as descriptions, object detection, or visual question answering.
**Base class:** `VisionService`
**Example:**
- [MoondreamVisionService](https://github.com/pipecat-ai/pipecat/blob/main/src/pipecat/services/moondream/vision.py)
#### Key requirements:
- Must implement `run_vision` method that takes an `LLMContext` and returns an `AsyncGenerator[Frame, None]`
- The method processes the latest image in the context and yields frames with analysis results
- Typically yields `TextFrame` objects containing descriptions or answers
## Implementation Guidelines
### Naming Conventions
- **STT:** `VendorSTTService`
- **LLM:** `VendorLLMService`
- **TTS:**
- Websocket: `VendorTTSService`
- HTTP: `VendorHttpTTSService`
- **Image:** `VendorImageGenService`
- **Vision:** `VendorVisionService`
- **Telephony:** `VendorFrameSerializer`
### Metrics Support
Enable metrics in your service:
```python
def can_generate_metrics(self) -> bool:
"""Check if this service can generate processing metrics.
Returns:
True, as this service supports metrics.
"""
return True
```
### Dynamic Settings Updates
STT, LLM, and TTS services support `ServiceUpdateSettingsFrame` for dynamic configuration changes. The base STTService has an `_update_settings()` method that handles settings, and the private `_settings` `Dict` is used to store settings and provide access to the subclass.
```python
async def set_language(self, language: Language):
"""Set the recognition language and reconnect.
Args:
language: The language to use for speech recognition.
"""
logger.info(f"Switching STT language to: [{language}]")
self._settings["language"] = language
await self._disconnect()
await self._connect()
```
Note that, in this example, Deepgram requires the websocket connection be disconnected and reconnected to reinitialize the service with the new value. Consider if your service requires reconnection.
### Sample Rate Handling
Sample rates are set via PipelineParams and passed to each frame processor at initialization. The pattern is to _not_ set the sample rate value in the constructor of a given service. Instead, use the `start()` method to initialize sample rates from the frame:
```python
async def start(self, frame: StartFrame):
"""Start the service."""
await super().start(frame)
self._settings["output_format"]["sample_rate"] = self.sample_rate
await self._connect()
```
Note that `self.sample_rate` is a `@property` set in the TTSService base class, which provides access to the private sample rate value obtained from the StartFrame.
### Tracing Decorators
Use Pipecat's tracing decorators:
- **STT:** `@traced_stt` - decorate a function that handles `transcript`, `is_final`, `language` as args
- **LLM:** `@traced_llm` - decorate the `_process_context()` method
- **TTS:** `@traced_tts` - decorate the `run_tts()` method
## Best Practices
### Packaging and Distribution
- Use [uv](https://docs.astral.sh/uv/) for packaging (encouraged)
- Consider releasing to PyPI for easier installation
- Follow semantic versioning principles
- Maintain a changelog
### HTTP Communication
For REST-based communication, use aiohttp. Pipecat includes this as a required dependency, so using it prevents adding an additional dependency to your integration.
### Error Handling
- Wrap API calls in appropriate try/catch blocks
- Handle rate limits and network failures gracefully
- Provide meaningful error messages
- When errors occur, raise exceptions AND push `ErrorFrame`s to notify the pipeline:
```python
from pipecat.frames.frames import ErrorFrame
try:
# Your API call
result = await self._make_api_call()
except Exception as e:
# Push error frame to pipeline
await self.push_error(ErrorFrame(error=f"{self} error: {e}"))
# Raise or handle as appropriate
raise
```
### Testing
- Your foundational example serves as a valuable integration-level test
- Unit tests are nice to have. As the Pipecat teams provides better guidance, we will encourage unit testing more
## Disclaimer
Community integrations are community-maintained and not officially supported by the Pipecat team. Users should evaluate these integrations independently. The Pipecat team reserves the right to remove listings that become unmaintained or problematic.
## Staying Up to Date
Pipecat evolves rapidly to support the latest AI technologies and patterns. While we strive to minimize breaking changes, they do occur as the framework matures.
**We strongly recommend:**
- Join our Discord at https://discord.gg/pipecat and monitor the `#announcements` channel for release notifications
- Follow our changelog: https://github.com/pipecat-ai/pipecat/blob/main/CHANGELOG.md
- Test your integration against new Pipecat releases promptly
- Update your README with the last tested Pipecat version
This helps ensure your integration remains compatible and your users have clear expectations about version support.

## Dependency Management
This project uses [uv](https://docs.astral.sh/uv/) for dependency management. The `uv.lock` file is committed to ensure reproducible builds.
### Adding or Updating Dependencies
1. Edit `pyproject.toml` to add/update dependencies
2. Run `uv lock` to update the lockfile with new dependency resolution
3. Run `uv sync` to install the updated dependencies locally
4. Always commit both files together:
```bash
git add pyproject.toml uv.lock
git commit -m "feat: add new dependency for feature X"
```
**Important:** Never manually edit `uv.lock`. It's auto-generated by `uv lock`.
## Code Style and Documentation
### Python Code Style
We use Ruff for code linting and formatting. Please ensure your code passes all linting checks before submitting a PR.
### Docstring Conventions
We follow Google-style docstrings with these specific conventions:
**Regular Classes:**
- Class docstring describes the class purpose and key functionality
- `__init__` method has its own docstring with complete `Args:` section documenting all parameters
- All public methods must have docstrings with `Args:` and `Returns:` sections as appropriate
**Dataclasses:**
- Class docstring describes the purpose and documents all fields in a `Parameters:` section
- No `__init__` docstring (auto-generated)
**Properties:**
- Must have docstrings with `Returns:` section
**Abstract Methods:**
- Must have docstrings explaining what subclasses should implement
**`__init__.py` Files:**
- **Skip docstrings** for pure import/re-export modules
- **Add brief docstrings** for top-level packages or those with initialization logic
**Enums:**
- Class docstring describes the enumeration purpose
- Use `Parameters:` section to document each enum value and its meaning
- No `__init__` docstring (Enums don't have custom constructors)
**Code Examples in Docstrings:**
- Use `Examples:` as a section header for multiple examples
- Use descriptive text followed by double colons (`::`) for each example
- **Always include a blank line after the `::"`**
- Indent all code consistently within each block
- Separate multiple examples with blank lines for readability
**Lists and Bullets in Docstrings:**
- Use dashes (`-`) for bullet points, not asterisks (`*`)
- **Add a blank line before bullet lists** when they follow a colon
- Use section headers like "Supported features:" or "Behavior:" before lists
- For complex nested information, consider using paragraph format instead
**Deprecations:**
- Use `warnings.warn()` in code for runtime deprecation warnings
- Add `.. deprecated::` directive in docstrings for documentation visibility
- Include version information and describe current status
- Describe parameters in present tense, use directive to indicate deprecation status
#### Examples:
```python
# Regular class
class MyService(BaseService):
"""Description of what the service does.

## Getting started
You can get started with Pipecat running on your local machine, then move your agent processes to the cloud when youre ready. You can also add a 📞 telephone number, 🖼️ image output, 📺 video input, use different LLMs, and more.
```shell
# Install the module
pip install pipecat-ai
# Set up your environment
cp dot-env.template .env
```
To keep things lightweight, only the core framework is included by default. If you need support for third-party AI services, you can add the necessary dependencies with:
```shell
pip install "pipecat-ai[option,...]"
```

## 🛠️ Contributing to the framework
## A simple voice agent running locally
### Prerequisites
Here is a very basic Pipecat bot that greets a user when they join a real-time session. We'll use [Daily](https://daily.co) for real-time media transport, and [Cartesia](https://cartesia.ai/) for text-to-speech.
**Minimum Python Version:** 3.10
**Recommended Python Version:** 3.12
```python
import asyncio
### Setup Steps
from pipecat.frames.frames import TextFrame
from pipecat.pipeline.pipeline import Pipeline
from pipecat.pipeline.task import PipelineTask
from pipecat.pipeline.runner import PipelineRunner
from pipecat.services.cartesia import CartesiaTTSService
from pipecat.transports.services.daily import DailyParams, DailyTransport
1. Clone the repository and navigate to it:
async def main():
# Use Daily as a real-time media transport (WebRTC)
transport = DailyTransport(
room_url=...,
token="", # leave empty. Note: token is _not_ your api key
bot_name="Bot Name",
params=DailyParams(audio_out_enabled=True))
```bash
git clone https://github.com/pipecat-ai/pipecat.git
cd pipecat
```
# Use Cartesia for Text-to-Speech
tts = CartesiaTTSService(
api_key=...,
voice_id=...
)
2. Install development and testing dependencies:
# Simple pipeline that will process text to speech and output the result
pipeline = Pipeline([tts, transport.output()])
```bash
uv sync --group dev --all-extras \
--no-extra gstreamer \
--no-extra krisp \
--no-extra local \
--no-extra ultravox # (ultravox not fully supported on macOS)
```
# Create Pipecat processor that can run one or more pipelines tasks
runner = PipelineRunner()
3. Install the git pre-commit hooks:
# Assign the task callable to run the pipeline
task = PipelineTask(pipeline)
```bash
uv run pre-commit install
```
# Register an event handler to play audio when a
# participant joins the transport WebRTC session
@transport.event_handler("on_first_participant_joined")
async def on_first_participant_joined(transport, participant):
participant_name = participant.get("info", {}).get("userName", "")
# Queue a TextFrame that will get spoken by the TTS service (Cartesia)
await task.queue_frame(TextFrame(f"Hello there, {participant_name}!"))
> **Note**: Some extras (local, gstreamer) require system dependencies. See documentation if you encounter build errors.
# Register an event handler to exit the application when the user leaves.
@transport.event_handler("on_participant_left")
async def on_participant_left(transport, participant, reason):
await task.cancel()
# Run the pipeline task
await runner.run(task)
if __name__ == "__main__":
asyncio.run(main())
```
Run it with:
```shell
python app.py
```
Daily provides a prebuilt WebRTC user interface. While the app is running, you can visit at `https://<yourdomain>.daily.co/<room_url>` and listen to the bot say hello!
## WebRTC for production use
WebSockets are fine for server-to-server communication or for initial development. But for production use, youll need client-server audio to use a protocol designed for real-time media transport. (For an explanation of the difference between WebSockets and WebRTC, see [this post.](https://www.daily.co/blog/how-to-talk-to-an-llm-with-your-voice/#webrtc))
One way to get up and running quickly with WebRTC is to sign up for a Daily developer account. Daily gives you SDKs and global infrastructure for audio (and video) routing. Every account gets 10,000 audio/video/transcription minutes free each month.
Sign up [here](https://dashboard.daily.co/u/signup) and [create a room](https://docs.daily.co/reference/rest-api/rooms) in the developer Dashboard.
## Hacking on the framework itself
_Note: You may need to set up a virtual environment before following these instructions. From the root of the repo:_
```shell
python3 -m venv venv
source venv/bin/activate
```
Install the development dependencies:
```shell
pip install -r dev-requirements.txt
```
Install the git pre-commit hooks (these help ensure your code follows project rules):
```shell
pre-commit install
```
Install the `pipecat-ai` package locally in editable mode:
```shell
pip install -e .
```
The `-e` or `--editable` option allows you to modify the code without reinstalling.
To include optional dependencies, add them to the install command. For example:
```shell
pip install -e ".[daily,deepgram,cartesia,openai,silero]" # Updated for the services you're using
```
If you want to use this package from another directory:
```shell
pip install "path_to_this_repo[option,...]"
```
### Running tests
To run all tests, from the root directory:
From the root directory, run:
```bash
uv run pytest
```shell
pytest
```
Run a specific test suite:
## Setting up your editor
```bash
uv run pytest tests/test_name.py
This project uses strict [PEP 8](https://peps.python.org/pep-0008/) formatting via [Ruff](https://github.com/astral-sh/ruff).
### Emacs
You can use [use-package](https://github.com/jwiegley/use-package) to install [emacs-lazy-ruff](https://github.com/christophermadsen/emacs-lazy-ruff) package and configure `ruff` arguments:
```elisp
(use-package lazy-ruff
:ensure t
:hook ((python-mode . lazy-ruff-mode))
:config
(setq lazy-ruff-format-command "ruff format")
(setq lazy-ruff-check-command "ruff check --select I"))
```
## 🤝 Contributing
`ruff` was installed in the `venv` environment described before, so you should be able to use [pyvenv-auto](https://github.com/ryotaro612/pyvenv-auto) to automatically load that environment inside Emacs.
```elisp
(use-package pyvenv-auto
:ensure t
:defer t
:hook ((python-mode . pyvenv-auto-run)))
```
### Visual Studio Code
Install the
[Ruff](https://marketplace.visualstudio.com/items?itemName=charliermarsh.ruff) extension. Then edit the user settings (_Ctrl-Shift-P_ `Open User Settings (JSON)`) and set it as the default Python formatter, and enable formatting on save:
```json
"[python]": {
"editor.defaultFormatter": "charliermarsh.ruff",
"editor.formatOnSave": true
}
```
### PyCharm
`ruff` was installed in the `venv` environment described before, now to enable autoformatting on save, go to `File` -> `Settings` -> `Tools` -> `File Watchers` and add a new watcher with the following settings:
1. **Name**: `Ruff formatter`
2. **File type**: `Python`
3. **Working directory**: `$ContentRoot$`
4. **Arguments**: `format $FilePath$`
5. **Program**: `$PyInterpreterDirectory$/ruff`

# Pipecat architecture guide
## Frames
Frames can represent discrete chunks of data, for instance a chunk of text, a chunk of audio, or an image. They can also be used to as control flow, for instance a frame that indicates that there is no more data available, or that a user started or stopped talking. They can also represent more complex data structures, such as a message array used for an LLM completion.
## FrameProcessors
Frame processors operate on frames. Every frame processor implements a `process_frame` method that consumes one frame and produces zero or more frames. Frame processors can do simple transforms, such as concatenating text fragments into sentences, or they can treat frames as input for an AI Service, and emit chat completions based on message arrays or transform text into audio or images.
## Pipelines
Pipelines are lists of frame processors linked together. Frame processors can push frames upstream or downstream to their peers. A very simple pipeline might chain an LLM frame processor to a text-to-speech frame processor, with a transport as an output.
## Transports
Transports provide input and output frame processors to receive or send frames respectively. For example, the `DailyTransport` does this with a WebRTC session joined to a Daily.co room.

# A Frame's Progress
1. A user says “Hello, LLM” and the cloud transcription service delivers a transcription to the Transport.
![A transcript frame arrives](images/frame-progress-01.png)
2. The Transport places a Transcription frame in the Pipelines source queue.
![Frame in source queue](images/frame-progress-02.png)
3. The Pipeline passes the Transcription frame to the first Frame Processor in its list, the LLM User Message Aggregator.
![To UMA](images/frame-progress-03.png)
4. The LLM User Message Aggregator updates the LLM Context with a `{“user”: “Hello LLM”}` message.
![Update context](images/frame-progress-04.png)
5. The LLM User Message Aggregator yields an LLM Message Frame, containing the updated LLM Context. The Pipeline passes this frame to the LLM Frame Processor.
![Update context](images/frame-progress-05.png)
6. The LLM Frame Processor creates a streaming chat completion based on the LLM context and yields the first chunk of a response, Text Frame with the value “Hi, “. The Pipeline passes this frame to the TTS Frame Processor. The TTS Frame Processor aggregates this response but doesnt yield anything, yet, because its waiting for a full sentence.
![LLM yields Text](images/frame-progress-06.png)
7. The LLM Frame Processor yields another Text Frame with the value “there.”. The Pipeline passes this frame to the TTS Frame Processor.
![LLM yields more Text](images/frame-progress-07.png)
8. The TTS Frame Processor now has a full sentence, so it starts streaming audio based on “Hi, there.” It yields the first chunk of streaming audio as an Audio frame, which the Pipeline passes to the LLM Assistant Message Aggregator.
![TTS yields Audio](images/frame-progress-08.png)
9. The LLM Assistant Message Aggregator doesnt do anything with Audio frames, so it immediately yields the frame, unchanged. This is the convention for all Frame Processors: frames that the processor doesnt process should be immediately yielded.
![pass-through](images/frame-progress-09.png)
10. The Pipeline places the first Audio frame in its sink queue, which is being watched by the Transport. Since the frame is now in a queue, the Pipeline can continue processing other frames. Note that the source and sink queues form a sort of “boundary of concurrent processing” between a Pipeline and the outside world. In a Pipeline, Frames are processed sequentially; once a Frame is on a queue it can be processed in parallel with the frames being processed by the Pipeline. TODO: link to a more in-depth section about this.
![sink queue](images/frame-progress-10.png)
11. The TTS Frame Processor yields another Audio frame as the Transport transmits the first Audio frame.
![parallel audio](images/frame-progress-11.png)
12. As before, the LLM Assistant Message Aggregator immediately yields the Audio frame and the Pipeline places the Audio frame in the sink queue.
![sink queue 2](images/frame-progress-12.png)
13. The TTS Frame Processor has no more frames to yield. The LLM Frame Processor emits an LLM Response End Frame, which the Pipeline passes to the TTS Frame Processor.
![response end](images/frame-progress-13.png)
14. The TTS Frame Processor immediately yields the LLM Response End Frame, so the Pipeline passes it along to the LLM Assistant Message Aggregator. The LLM Assistant Message Aggregator updates the LLM Context with the full response from the LLM. TODO TODO: I realized I forgot that the TSS Frame Processor also yields the Text frames that the LLM emitted so that the LLM Assistant Message Aggregator could accumulate them, arrggh.
![response end](images/frame-progress-14.png)
15. The system is quiet, and waiting for the next message from the Transport.

# Understanding Different Frame Types in the Pipecat System
In the Pipecat system, frames are used to represent different types of data and control signals that flow through the pipeline. Understanding these frame types is crucial for working with the system effectively. This tutorial will cover the main categories of frames and their specific uses.
## 1. Base Frame Classes
### Frame
The `Frame` class is the base class for all frames. It includes:
- `id`: A unique identifier
- `name`: A descriptive name
- `pts`: Presentation timestamp (optional)
### DataFrame
`DataFrame` is a subclass of `Frame` and serves as a base for most data-carrying frames.
## 2. Audio Frames
### AudioRawFrame
Represents a chunk of audio with properties:
- `audio`: Raw audio data
- `sample_rate`: Audio sample rate
- `num_channels`: Number of audio channels
Subclasses include:
- `InputAudioRawFrame`: For audio from input sources
- `OutputAudioRawFrame`: For audio to be played by output devices
- `TTSAudioRawFrame`: For audio generated by Text-to-Speech services
## 3. Image Frames
### ImageRawFrame
Represents an image with properties:
- `image`: Raw image data
- `size`: Image dimensions
- `format`: Image format (e.g., JPEG, PNG)
Subclasses include:
- `InputImageRawFrame`: For images from input sources
- `OutputImageRawFrame`: For images to be displayed
- `UserImageRawFrame`: For images associated with a specific user
- `VisionImageRawFrame`: For images with associated text for description
- `URLImageRawFrame`: For images with an associated URL
### SpriteFrame
Represents an animated sprite, containing a list of `ImageRawFrame` objects.
## 4. Text and Transcription Frames
### TextFrame
Represents a chunk of text, used for various purposes in the pipeline.
### TranscriptionFrame
A specialized `TextFrame` for speech transcriptions, including:
- `user_id`: ID of the speaking user
- `timestamp`: When the transcription was generated
- `language`: Detected language of the speech
### InterimTranscriptionFrame
Similar to `TranscriptionFrame`, but for interim (not final) transcriptions.
## 5. LLM (Language Model) Frames
### LLMMessagesFrame
Contains a list of messages for an LLM service to process.
### LLMMessagesAppendFrame and LLMMessagesUpdateFrame
Used to modify the current context of LLM messages.
### LLMSetToolsFrame
Specifies tools (functions) available for the LLM to use.
### LLMEnablePromptCachingFrame
Controls prompt caching in certain LLMs.
## 6. System and Control Frames
### SystemFrame
Base class for system-level frames.
Important system frames include:
- `StartFrame`: Initiates a pipeline
- `CancelFrame`: Stops a pipeline immediately
- `ErrorFrame`: Notifies of errors (with `FatalErrorFrame` for unrecoverable errors)
- `EndTaskFrame` and `CancelTaskFrame`: Control pipeline tasks
- `StartInterruptionFrame` and `StopInterruptionFrame`: Indicate user speech for interruptions
### ControlFrame
Base class for control-flow frames.
Notable control frames:
- `EndFrame`: Signals the end of a pipeline
- `LLMFullResponseStartFrame` and `LLMFullResponseEndFrame`: Bracket LLM responses
- `UserStartedSpeakingFrame` and `UserStoppedSpeakingFrame`: Indicate user speech activity
- `BotStartedSpeakingFrame` and `BotStoppedSpeakingFrame`: Indicate bot speech activity
- `TTSStartedFrame` and `TTSStoppedFrame`: Bracket Text-to-Speech responses
## 7. Special Purpose Frames
### MetricsFrame
Contains performance metrics data.
### FunctionCallInProgressFrame and FunctionCallResultFrame
Used for handling LLM function (tool) calls.
### ServiceUpdateSettingsFrame
Base class for updating service settings, with specific subclasses for LLM, TTS, and STT services.
## Conclusion
Understanding these frame types is essential for working with the Pipecat system. Each frame type serves a specific purpose in the pipeline, whether it's carrying data (like audio or images), controlling the flow of the pipeline, or managing system-level operations. By using the appropriate frame types, you can effectively process and transmit various kinds of information through your pipeline.

docker push ...
```
### SSL
If you're working with a custom UI (such as with the Storytelling Chatbot), it's important to ensure your deployment platform supports HTTPS, as accessing user devices such as mics and webcams requires SSL.
If you try to run a custom UI without SSL, you may see an error in the console telling you that `navigator` is undefined, or no devices are available.
### Are these examples production ready?
Yes, kind of.
These demos attempt to keep things simple and are unopinionated regarding environment or scalability.
We're using FastAPI to spawn a subprocess for the bots / agents &mdash; useful for small tests, but not so great for production grade apps with many concurrent users. You can see how this works in each project's `start` endpoint in `server.py`.
Creating virtualized worker pools and on-demand instances is out of scope for these examples, but we hope to add some examples to this repo soon!
For projects that have CUDA as a requirement, such as Moondream Chatbot, be sure to deploy to a GPU-powered platform (such as [fly.io](https://fly.io) or [Runpod](https://runpod.io).)

# Bot ready signaling
A simple Pipecat example demonstrating how to handle signaling between the client and the bot,
ensuring that the bot starts sending audio only when the client is available,
thereby avoiding the risk of cutting off the beginning of the audio.
## Quick Start
### First, start the bot server:
1. Navigate to the server directory:
```bash
cd server
```
2. Create and activate a virtual environment:
```bash
python3 -m venv venv
source venv/bin/activate # On Windows: venv\Scripts\activate
```
3. Install requirements:
```bash
pip install -r requirements.txt
```
4. Copy env.example to .env and configure:
- Add your API keys
5. Start the server:
```bash
python server.py
```
### Next, connect using the client app:
For client-side setup, refer to the [JavaScript Guide](client/javascript/README.md).
## Important Note
Ensure the bot server is running before using any client implementations.
## Requirements
- Python 3.10+
- Node.js 16+ (for JavaScript)
- Daily API key
- Cartesia API key
- Modern web browser with WebRTC support

# JavaScript Implementation
Basic implementation using the [Pipecat JavaScript SDK](https://docs.pipecat.ai/client/js/introduction).
## Setup
1. Run the bot server. See the [server README](../../README).
2. Navigate to the `client/javascript` directory:
```bash
cd client/javascript
```
3. Install dependencies:
```bash
npm install
```
4. Run the client app:
```
npm run dev
```
5. Visit http://localhost:5173 in your browser.

# Chatbot with canonical-metrics
This project implements a chatbot using a pipeline architecture that integrates audio processing, transcription, and a language model for conversational interactions. The chatbot operates within a daily communication environment, utilizing various services for text-to-speech and language model responses.
## Features
- **Audio Input and Output**: Captures microphone input and plays back audio responses.
- **Voice Activity Detection**: Utilizes Silero VAD to manage audio input intelligently.
- **Text-to-Speech**: Integrates ElevenLabs TTS service to convert text responses into audio.
- **Language Model Interaction**: Uses OpenAI's GPT-4 model to generate responses based on user input.
- **Transcription Services**: Captures and transcribes participant speech for analytics.
- **Metrics Collection**: Sends audio data for analysis via Canonical Metrics Service.
## Requirements
- Python 3.10+
- `python-dotenv`
- Additional libraries from the `pipecat` package.
## Setup
1. Clone the repository.
2. Install the required packages.
3. Set up environment variables for API keys:
- `OPENAI_API_KEY`
- `ELEVENLABS_API_KEY`
- `CANONICAL_API_KEY`
- `CANONICAL_API_URL`
4. Run the script.
## Usage
The chatbot introduces itself and engages in conversations, providing brief and creative responses. Designed for flexibility, it can support multiple languages with appropriate configuration.
## Events
- Participants joining or leaving the call are handled dynamically, adjusting the chatbot's behavior accordingly.
The first time, things might take extra time to get started since VAD (Voice Activity Detection) model needs to be downloaded.
## Get started
```python
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
cp env.example .env # and add your credentials
```
## Run the server
```bash
python server.py
```
Then, visit `http://localhost:7860/` in your browser to start a chatbot session.
## Build and test the Docker image
```
docker build -t chatbot .
docker run --env-file .env -p 7860:7860 chatbot
```

# Simple Chatbot
<img src="image.png" width="420px">
This app connects you to a chatbot powered by GPT-4, complete with animations generated by Stable Video Diffusion.
See a video of it in action: https://x.com/kwindla/status/1778628911817183509
And a quick video walkthrough of the code: https://www.loom.com/share/13df1967161f4d24ade054e7f8753416
The first time, things might take extra time to get started since VAD (Voice Activity Detection) model needs to be downloaded.
## Get started
```python
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
cp env.example .env # and add your credentials
```
## Run the server
```bash
python server.py
```
Then, visit `http://localhost:7860/` in your browser to start a chatbot session.
## Build and test the Docker image
```
docker build -t chatbot .
docker run --env-file .env -p 7860:7860 chatbot

# Fly.io deployment example
This project modifies the `bot_runner.py` server to launch a new machine for each user session. This is a recommended approach for production vs. running shell processess as your deployment will quickly run out of system resources under load.
For this example, we are using Daily as a WebRTC transport and provisioning a new room and token for each session. You can use another transport, such as WebSockets, by modifying the `bot.py` and `bot_runner.py` files accordingly.
## Setting up your fly.io deployment
### Create your fly.toml file
You can copy the `example-fly.toml` as a reference. Be sure to change the app name to something unique.
### Create your .env file
Copy the base `env.example` to `.env` and enter the necessary API keys.
`FLY_APP_NAME` should match that in the `fly.toml` file.
### Launch a new fly.io project
`fly launch` or `fly launch --org your-org-name`
### Set the necessary app secrets from your .env
Note: you can do this manually via the fly.io dashboard under the "secrets" sub-section of your deployment (e.g. "https://fly.io/apps/fly-app-name/secrets") or run the following terminal command:
`cat .env | tr '\n' ' ' | xargs flyctl secrets set`
### Deploy your machine
`fly deploy`
## Connecting to your bot
Send a post request to your running fly.io instance:
`curl --location --request POST 'https://YOUR_FLY_APP_NAME/'`
This request will wait until the machine enters into a `starting` state, before returning the a room URL and token to join.

# Deploying Pipecat to Modal.com
Barebones deployment example for [modal.com](https://www.modal.com)
1. Install dependencies
```bash
python -m venv venv
source venv/bin/active # or OS equivalent
pip install -r requirements.txt
```
2. Setup .env
```bash
cp env.example .env
```
Alternatively, you can configure your Modal app to use [secrets](https://modal.com/docs/guide/secrets)
3. Test the app locally
```bash
modal serve app.py
```
4. Deploy to production
```bash
modal deploy app.py
```
## Configuration options
This app sets some sensible defaults for reducing cold starts, such as `minkeep_warm=1`, which will keep at least 1 warm instance ready for your bot function.
It has been configured to only allow a concurrency of 1 (`max_inputs=1`) as each user will require their own running function.
