FastRTC is a Python library that turns any Python function into a real-time audio and video stream over WebRTC or WebSockets. It includes built-in voice activity detection, turn-taking, an auto-launched Gradio UI, and easy mounting on FastAPI apps for custom frontends.

Use cases

• build a real-time voice chatbot with an LLM
• stream webcam audio and video to a multimodal AI model
• add speech-to-text and text-to-speech to a Python app
• create a phone-callable voice assistant
• mount a WebRTC endpoint on a FastAPI backend
• prototype voice agents with automatic pause detection

When to choose

• you want to build real-time audio/video AI applications in Python with minimal boilerplate
• you need built-in voice detection, turn-taking, and TTS/VAD extras
• you want a quick Gradio UI plus the option to mount on FastAPI for production

When to avoid

• you need a non-Python stack or fine-grained low-level WebRTC control
• your use case is offline batch audio/video processing rather than live streaming
• you need production telephony features beyond the temporary free phone number
