Raven
Try encrypted messaging in an open MainNet beta. Messages cost real ALGO; use only low-sensitivity information.

An older two-client LocalNet demonstration. Kept so the progression is visible. The app people open today is the Get started screen above.
How it has lived
Recorded as a usable beta
The owner review recorded Raven as a usable beta on MainNet. No Nevermore is required to try it. Messages cost real ALGO.
About page pinned at v0.12.0
The about page pinned the open beta at v0.12.0. The web app stayed on this site because raven.corvidlabs.xyz was not serving it.
About page pinned at v0.15.1
The about page pin moved to v0.15.1. Desktop packages linked from that page were 0.14.2. The web app stayed at /algorand/raven/.
A new chat is a hybrid session
The about page says a new chat starts as a hybrid session: X25519 plus ML-KEM-768, then ChaCha20-Poly1305. Everyday chat and Extra lock stay choices. Extra lock is not a stronger post-quantum choice than a hybrid session.
About page pinned at v0.17.0
The about page now pins the open beta at v0.17.0. Desktop packages on that page are still 0.14.2. The visit door is the full-screen place for the web app.

The hybrid start, in writing
The about page still pins v0.17.0. Desktop packages are still 0.14.2. The write-up says what a new chat starts as, and that Extra lock is not a stronger post-quantum choice than that hybrid session.
