Does matrix have forward secrery now since the switch to MLS? (I.E. the same encryption scheme Singal uses) https://matrix.org/blog/2025/06/dispelling-myths/
They still have a large metadata leak that to my understanding can’t be fixed until they introduce stuff like pseudo anonymous user handles and room handles.
Not a good discord replacement but setting up nextcloud talk (simple p2p voice chat) and then the high performance backend (better supports video/voice calls between 3+ people) was relatively easy. We use it among my family now to have group calls instead of relying on facebook messenger.
If you use the AIO it comes with the high performance backend already set up afaik.
I run nextcloud using the official release without the docket AIO image, but you can just run the high performance backend from docker. This is what I do on my nextcloud server. https://arnowelzel.de/en/nextcloud-talk-high-performance-backend-with-docker
It’s pretty straightforward, just run docker container, if you use a reverse proxy much sure the signaling server is properly configured on the reverse proxy and then modify the next cloud settings to point to the self hosted HPB.
If OP wants voice and video chat like they say they’d have to host synapse and use element afaik.i don’t think any of the other home servers support matrix calling. Cinny and fluffychat don’t support voice or video calls. Fluffychat has it as an “option” but it’s currently broken last time I tried it. Schildi chat might work for voice and video since it’s an element fork. I’ve not tried it so I don’t know for sure.
Do the voice call and video features work with continuwuity?
You’re right, I was wrong about signal using MLS. I recall reading it somewhere but can’t find the source now.
As for my response, it was about forward secrecy which they do claim to have now. Yeah I wouldn’t rely on matrix E2EE right now, and until its been seriously audited and replaced with something security experts agree on.
For a discord replacement (with public not E2EE rooms) it seems to be the best replacement just because that’s where communities are right now. XMPP+OMEMO is not that interesting to me because I don’t know of any communities that are on there or other users to be a Discord replacement and its E2EE story is not as good as Signal to be a Signal replacement.
For a signal replacement I’m not sure SimpleX or Briar are there yet. SimpleX doesn’t have multi device support last time I checked which is annoying if you’re used to useing signal on your phone + desktop. Any Briar doesn’t work on IOS, so if you chat with anyone who has an iphone they are SOL.
