Real-time latency at CDN scale, for video, audio, and any live data.
Independent QUIC streams let congestion drop old media instead of delaying new media, while tiny single-frame groups can use datagrams.
Relays cache and fan out broadcasts without understanding the payload, and cluster across regions.
Generic pub/sub underneath, media on top. Add your own tracks for chat, input, telemetry, or AI output.
Browsers via WebTransport, native apps via Rust and language bindings, plus gateways to RTMP, SRT, HLS, and WebRTC.
Media over QUIC (MoQ) is a live media protocol built on QUIC. A publisher sends a broadcast made of tracks; each track is a series of groups (a group of pictures, a second of audio, one JSON snapshot). Most groups use independent QUIC streams; eligible single-frame groups can use unreliable datagrams. Relays forward and cache the stream-delivered groups without parsing them, so the same infrastructure carries video, audio, and arbitrary data.
This project is the reference implementation: a Rust relay and toolchain, a TypeScript browser stack, and bindings for C, Python, Kotlin, Swift, Go, and Dart. It speaks moq-lite, a simple profile that is forward-compatible with the IETF moq-transport drafts.
| Use case | Reach for |
|---|---|
| Twitch-style live streaming | Ingest with OBS, RTMP or SRT, distribute with moq-relay, watch with <moq-watch>, and keep legacy players via the HLS gateway. |
| Conferencing | <moq-publish> and <moq-watch> in the browser, one broadcast per participant, plus the WebRTC gateway for WHIP/WHEP clients. |
| Voice and video AI | Server-side media in Rust or Python with hardware codecs, faster-than-real-time playback in the browser. See MoQ for AI. |
| Real-time data | Chat, game state, telemetry, and control channels over the same relays with moq-net or @moq/net. |
| Interactive streams | Media down, input up. MoQ Boy is a crowd-controlled Game Boy built this way. |
| Native and mobile apps | One Rust core behind Swift, Kotlin, Go, Dart, and C bindings. |
