moq-rs

moq-rs is a Rust implementation of the MoQ Transport protocol created at Cloudflare. It provides both a relay server and a client library for building MoQ-based applications.

The project includes a fully functional relay that can route MoQ traffic between publishers and subscribers, as well as a Rust client library for connecting to relays programmatically.

Key features

• Full relay implementation with pub/sub routing
• Rust client library for MoQ Transport
• WebTransport and raw QUIC support via Quinn
• CMAF-based streaming with JSON catalog
• Multi-draft compatibility
• Active participant in MoQ interop testing

Public relays

Cloudflare runs a separate public deployment per draft, listed below with what each answered the last time the moqtap TestLab sweep measured it. main targets draft-16, and the draft-16 deployment is the basis of the production service; the draft-18 endpoint is an interop endpoint rather than a production relay.

The deployments run roughly one to two weeks behind main, so what an endpoint answers on a given day and what this repository does at HEAD are different things, and a result measured on one of them is not a result about this codebase.

Documentation for the endpoints is at developers.cloudflare.com/moq.
