# 🎙️ Pipecat: Real-Time Voice & Multimodal AI Agents

**Pipecat** is an open-source Python framework for building real-time voice and multimodal conversational agents. Orchestrate audio and video, AI services, different transports, and conversation pipelines effortlessly—so you can focus on what makes your agent unique.

> Want to dive right in? Try the [quickstart](https://docs.pipecat.ai/getting-started/quickstart).

## 🚀 What You Can Build

- **Voice Assistants** – natural, streaming conversations with AI
- **AI Companions** – coaches, meeting assistants, characters
- **Multimodal Interfaces** – voice, video, images, and more
- **Interactive Storytelling** – creative tools with generative media
- **Business Agents** – customer intake, support bots, guided flows
- **Complex Dialog Systems** – design logic with structured conversations

## 🧠 Why Pipecat?

- **Voice-first**: Integrates speech recognition, text-to-speech, and conversation handling
- **Pluggable**: Supports many AI services and tools
- **Composable Pipelines**: Build complex behavior from modular components
- **Real-Time**: Ultra-low latency interaction with different transports (e.g. WebSockets or WebRTC)

## ⚡ Getting started

You can get started with Pipecat running on your local machine, then move your agent processes to the cloud when you're ready.

1. Install uv

   ```bash
   curl -LsSf https://astral.sh/uv/install.sh | sh
   ```

   > **Need help?** Refer to the [uv install documentation](https://docs.astral.sh/uv/getting-started/installation/).

2. Install the module

   ```bash
   # For new projects
   uv init my-pipecat-app
   cd my-pipecat-app
   uv add pipecat-ai

   # Or for existing projects
   uv add pipecat-ai
   ```

3. Set up your environment

   ```bash
   cp env.example .env
   ```

4. 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:

   ```bash
   uv add "pipecat-ai[option,...]"
   ```

> **Using pip?** You can still use `pip install pipecat-ai` and `pip install "pipecat-ai[option,...]"` to get set up.

## 🧪 Code examples

- [Foundational](https://github.com/pipecat-ai/pipecat/tree/main/examples/foundational) — small snippets that build on each other, introducing one or two concepts at a time
- [Example apps](https://github.com/pipecat-ai/pipecat-examples) — complete applications that you can use as starting points for development

## 🛠️ Contributing to the framework

### Prerequisites

**Minimum Python Version:** 3.10
**Recommended Python Version:** 3.12

### Setup Steps

1. Clone the repository and navigate to it:

   ```bash
   git clone https://github.com/pipecat-ai/pipecat.git
   cd pipecat
   ```

2. Install development and testing dependencies:

   ```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)
   ```

3. Install the git pre-commit hooks:

   ```bash
   uv run pre-commit install
   ```

> **Note**: Some extras (local, gstreamer) require system dependencies. See documentation if you encounter build errors.

### Running tests

To run all tests, from the root directory:

```bash
uv run pytest
```

Run a specific test suite:

```bash
uv run pytest tests/test_name.py
```
