FastRTC turns any Python function into a real-time audio or video stream over WebRTC or WebSockets
Write a Python generator that takes audio (or video) frames and yields responses.
Install from PyPI, adding the vad/tts extras if you want pause detection and text-to-speech.
Create a Stream with ReplyOnPause for audio conversations, and pick a delivery mode: built-in UI, FastAPI mount, or a phone number.
Start the stream and speak to your function in real time.
Built-in voice activity detection (the ReplyOnPause handler) runs your function when the user stops speaking.
Stream real-time audio or video over either transport, in send, receive, or send-receive modes.
Every stream can launch with a test interface via stream.ui.launch().
Mount a stream into an existing FastAPI application with stream.mount(app).
Get a temporary phone number to call your stream, using a Hugging Face token.
Optional vad and tts extras add pause detection and text-to-speech support.
Clone the project and enter its directory (library users can install from PyPI instead).
git clone https://github.com/gradio-app/fastrtc.git
cd fastrtcInstall the package, with the speech extras if you need them.
pip install fastrtc
pip install "fastrtc[vad, tts]"Wrap a reply function in a Stream and launch the built-in UI.
from fastrtc import Stream, ReplyOnPause
stream = Stream(handler=ReplyOnPause(fn), modality="audio", mode="send-receive")
stream.ui.launch()The Gradio team (gradio-app) — the same group behind the Gradio ML interface library.
Yes, it is MIT-licensed open source. FastPhone numbers are provided through Hugging Face and require an HF token.
No — the library is self-contained; you supply your own speech/LLM models inside your handler function.
FastRTC abstracts the transport and adds the conversational layer — VAD, turn-taking, a test UI, and FastAPI mounting — so you write a plain function instead of managing peers and tracks.
`pip install fastrtc`, wrap your function with `Stream(handler=ReplyOnPause(fn), ...)`, and call `stream.ui.launch()`.
