MoQ is designed to be an Internet infrastructure level service that provides media delivery to applications, similar to how HTTP provides content delivery and WebRTC provides real-time communication.

Cloudflare's implementation of MoQ currently supports a subset of the [draft-07 MoQ Transport specfication](https://datatracker.ietf.org/doc/html/draft-ietf-moq-transport-07).

For the most up-to-date documentation on the protocol, please visit the IETF working group documentation.

## Frequently Asked Questions

* What about Safari?

Safari does not yet have fully functional WebTransport support. Apple never publicly commits to timelines for new features like this. However, Apple has indicated their [intent to support WebTransport](https://github.com/WebKit/standards-positions/issues/18#issuecomment-1495890122). An Apple employee is even a co-author of the [WebTransport over HTTP/3](https://datatracker.ietf.org/doc/draft-ietf-webtrans-http3/) draft. Since Safari 18.4 (2025-03-31), an early (not yet fully functional) implementation of the WebTransport API has been available for testing behind a developer-mode / advanced settings feature flag (including on iOS).

Until Safari has a fully functional WebTransport implementation, some MoQ use cases may require a fallback to WebRTC, or, in some cases, WebSockets.
