You can get started with Pipecat running on your local machine, then move your agent processes to the cloud when you're ready.
Install uv
curl -LsSf https://astral.sh/uv/install.sh | shNeed help? Refer to the uv install documentation.
Install the module
# For new projects uv init my-pipecat-app cd my-pipecat-app uv add pipecat-ai # Or for existing projects uv add pipecat-ai
Set up your environment
cp env.example .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:
uv add "pipecat-ai[option,...]"
Using pip? You can still use
pip install pipecat-aiandpip install "pipecat-ai[option,...]"to get set up.
- Foundational — small snippets that build on each other, introducing one or two concepts at a time
- Example apps — complete applications that you can use as starting points for development
Minimum Python Version: 3.10 Recommended Python Version: 3.12
Clone the repository and navigate to it:
git clone https://github.com/pipecat-ai/pipecat.git cd pipecatInstall development and testing dependencies:
uv sync --group dev --all-extras \ --no-extra gstreamer \ --no-extra krisp \ --no-extra local \ --no-extra ultravox # (ultravox not fully supported on macOS)
Install the git pre-commit hooks:
uv run pre-commit install
Note: Some extras (local, gstreamer) require system dependencies. See documentation if you encounter build errors.
To run all tests, from the root directory:
uv run pytestRun a specific test suite:
uv run pytest tests/test_name.pyWe welcome contributions from the community! Whether you're fixing bugs, improving documentation, or adding new features, here's how you can help:
