Pipecat Freemium

Pipecat is an open-source Python framework for building real-time voice and multimodal AI agents. It chains speech-to-text, an LLM and text-to-speech into one pipeline and handles the hard parts — interruption, barge-in and audio streaming.

What is Pipecat?

Building a voice bot from scratch means juggling WebRTC, VAD, turn detection and half a dozen APIs. Pipecat gives you composable “processors” you chain together: a transport, an STT service, an LLM, a TTS service. It was started by the team behind Daily’s WebRTC platform and is MIT licensed.

You write Python. It ships connectors for OpenAI, Anthropic, Deepgram, Cartesia, ElevenLabs and others.

Product Features

• Pipeline model: assemble frames and processors into a real-time graph.
• Interruption handling: detects barge-in and stops the bot mid-sentence.
• Many providers: swap STT, TTS and LLM services without rewriting logic.
• WebRTC transports: Daily, SmallWebRTC and WebSocket options.
• Multimodal: handles audio and video, not just speech.
• Observability: hooks into tracing tools for debugging live sessions.

Product Highlights

• Open source and free; you pay only the model providers you plug in.
• Latency-focused design, so replies feel conversational rather than laggy.
• Large set of ready-made service adapters.
• Active community and frequent releases.

Who should use Pipecat, and who should not?

It is aimed at developers who want control over a voice stack instead of a managed SaaS. If you cannot write Python or do not want to run servers, a no-code voice platform will serve you better. Pipecat is also a framework, not a hosted product — you own deployment, scaling and debugging.

Use Cases

• Building a low-latency phone support agent.
• Adding voice to an existing LLM app.
• Prototyping an interactive voice game or tutor.
• Running a real-time meeting assistant.
• Creating multimodal agents that see and hear.

Quick Summary

• Pipecat is an open-source Python framework for real-time voice AI.
• It chains STT, LLM and TTS into one pipeline with interruption handling.
• Supports OpenAI, Deepgram, Cartesia, ElevenLabs and more.
• For developers who want control; not a no-code tool.
• You pay per-API for the model providers you connect.
