I gave it another try last week
- the onboarding automatically creates a username/password on the server you selected, more details here: https://chaos.social/@delta/115479392746850836
- E2EE using openpgp
- fast and light on resources
It’s still in development, it’s not a fully fledged replacement for Matrix yet, but I could see it replace Signal at some point.
For a list of servers: https://chatmail.at/relays
If you wanna see if a server supports it just put in your servers URL into this handy matrix server tester.
If the server has something related to “livekit” in the .well-known section then its most likely supported.
