Web Application Integrity, Consistency and Transparency (WAICT)

You can test if your browser supports WAICT here, or you can check out 🍊 Orange Meets, a video conferencing platform by Cloudflare which uses MLS for E2EE and has been integrated with WAICT.

On the client side, an early prototype is available in Firefox Nightly. The prototype's current scope is outlined in this brief and you can follow future progress via the tracking bug. Other browsers have not yet indicated a position on WAICT.

WAICT has a set of draft specifications available on Github.
