What is Pipecat?

Pipecat (by Daily.co) provides a modular, transport-neutral pipeline for building voice agents. It passes audio, text, and control signals as frames through independent processors, making it highly extensible.

Key Features

Frame-based Composability: Chain, fork, and compose processors freely.
Transport-neutral: Run the same voice agent over WebRTC, WebSockets, or SIP/PSTN.
Multi-agent Support: Run parallel agents on a shared communication bus.

Pricing Estimate (2026)

Open-Source (BSD). Free to self-host. Managed cloud options and telephony transport incur usage fees depending on the provider.
