What Pipecat does
- Pipecat integrates speech recognition, text-to-speech, and conversation handling into streaming conversation pipelines built from modular components.
- Pipecat lets you swap speech, language, and vision services from many integrated providers, usually with one line of code.
- Pipecat supports multi-agent systems where each pipeline is an agent, composed through handoff, parallel fan-out, sidecar workers, or distributed deployments.
- Pipecat connects agents over transports such as Daily WebRTC, LiveKit, FastAPI WebSocket, WhatsApp, and local audio.
- Pipecat Flows, built into Pipecat, handles predefined or dynamic conversation paths with state management.
- Pipecat handles interruptions, turn detection, and context management, and reports metrics, traces, and OpenTelemetry data.
- Pipecat accepts files and images sent by clients and adds them to the LLM context, as of v1.13.0.
How it works
Pipecat runs as a Python process. It streams frames through a pipeline of services, and no stage waits on the one before it. You compose speech-to-text, LLM, and text-to-speech or speech-to-speech services, then connect a transport such as WebRTC or WebSockets. Clients connect through official SDKs for JavaScript, React, React Native, Swift, Kotlin, C++, and ESP32.
How to install and start using Pipecat
Add to a project with uv
uv add pipecat-aiInstall the CLI with uv
uv tool install "pipecat-ai[cli]"First steps
- Run `pipecat init quickstart` or follow the quickstart guide in the documentation.
- Run `pipecat init` and choose either to build with a coding agent or to scaffold a runnable bot right away.
- Pipecat init registers the Context Hub MCP server so your coding agent uses current Pipecat APIs.
- Use the Pipecat CLI to monitor your agent and deploy it to production.
Who Pipecat is for
- Python developers building real-time voice assistants or phone and support bots
- Teams building multi-agent voice systems with handoffs and parallel specialists
- Developers who want to mix and swap speech and LLM providers in one pipeline
- Projects that need multimodal input such as voice, video, and images
Limitations to know
- Pipecat's server framework is Python-only and requires Python 3.11 or later.
- Pipecat orchestrates external AI services, so speech and model quality depend on the providers you choose.
- Pipecat file messages raise errors for MIME types an LLM adapter does not support.
