MoQT Draft Support
Cloudflare operates public MoQ Transport relays running both draft-14 and draft-16 of the protocol globally. The draft-16 deployment is the one the moq-rs main branch targets — the repository states that the implementation targets draft-ietf-moq-transport-16 and that this forms the basis of the production deployment.
Relay endpoint
https://draft-16.cloudflare.mediaoverquic.com
Draft-18
Cloudflare also runs a separate draft-18 interop endpoint at draft-18-interop.cloudflare.mediaoverquic.com, exercised in the MoQ interop runner. As of the IETF 126 interop it was not yet at parity with the production relays: control-plane conformance passed and single-subscriber object delivery worked after moq-rs updates in July 2026, but delivery under concurrent subscribers still failed — with three subscribers, one SUBSCRIBE timed out and the receiving subscribers got a partial object set. Treat it as a development endpoint rather than a production relay.
