Overview
Pipecat is a high-performance, open-source Python and TypeScript framework for building real-time voice, video, and multimodal conversational AI agents. Maintained by Daily.co, Pipecat abstracts the intricate pipeline of WebRTC transport, audio turn-taking, speech-to-text (STT), LLM streaming, and text-to-speech (TTS) into modular, composable services.
Pipecat solves the hardest challenges in real-time conversational agents: human interruption handling, sub-second latency, voice activity detection (VAD), and network jitter over WebRTC and WebSockets. It offers plug-and-play integrations with Deepgram, Cartesia, ElevenLabs, OpenAI Realtime API, Whisper, and Anthropic Claude, allowing developers to construct voice bots for telephony, customer support, and interactive robotics.
LiveKit Agents is an open-source real-time communication framework engineered to build conversational voice, video, and multimodal AI agents with sub-500ms latency. Leveraging WebRTC, it connects speech-to-text (Deepgram, Whisper), LLMs (OpenAI, Anthropic), and text-to-speech (Cartesia, ElevenLabs) in a tightly synchronized bidirectional stream. From customer service avatars to interactive language tutors and hands-free coding copilots, LiveKit Agents provides the enterprise infrastructure for real-time human-AI interaction.
Building real-time voice agents requires solving audio interruption, packet jitter, and latency stacking. LiveKit Agents abstracts these challenges with native Voice Activity Detection (VAD), turn-taking management, and edge-routed audio pipelines. Available in Python and Node.js with client SDKs across React, iOS, Android, and Flutter, LiveKit enables developers to self-host their agent backend or deploy onto LiveKit Cloud.
