Our Matrix homeserver. Federated by default. End-to-end encrypted by choice.

What is Matrix

Matrix is an open protocol for federated, secure, real-time communication. Think of it like email — every server talks to every other server — except the conversation is live, the encryption is end-to-end, and the protocol is open enough that anyone can run their own server and still talk to everyone else. You don't sign up to one Matrix. You sign up to a homeserver. That homeserver is one of many. They all interoperate.

Why we run our own

Centralized chat services are a single party deciding who speaks, what's said, and which conversations vanish. We don't want that. We run our own homeserver because the rules of our rooms are ours. The data is on hardware we control. The encryption keys live on devices, not on someone else's compliance team's lap. If chat.sulkta.com goes away — and it won't — the protocol remains, and we can spin a new one up the same day.

What clients work

Any Matrix client speaks to chat.sulkta.com. Some good picks: • Element X (Android / iOS) — actively-developed, modern UI, end-to-end encryption first-class. Our default. • Element Web (browser) — same project, browser version. • Cinny, FluffyChat, SchildiChat — community clients, all federated, all interoperable. You log in to the client once, point it at chat.sulkta.com, and it handles the rest.

Who can join

chat.sulkta.com is invite-only. The coop runs it for members and people working with the coop — Sulkta family rooms, the AI room, the infra room, project rooms with collaborators. If you're already in a room, ask the person who invited you. If you think you should be in a room and aren't, that's a coordination problem, not a technical one — message the relevant human directly.

How it fits with the rest of Sulkta

Sign-in is the same Sulkta single sign-on you use for every other coop service. You authenticate once, your client gets a Matrix access token, and that token is what your client stores. Sessions are long-lived — measured in months — so you don't re-auth from your phone every week. Cross-signing keys, room keys, device verification — Matrix concepts, not Sulkta inventions. The Element X docs cover them better than we will.

If something breaks

Hit the bugs tracker at bugs.sulkta.com. We watch it. Or message the infra room directly if you're already in it — that's faster. If the homeserver itself is down (the whole domain unreachable), check status from outside the LAN to confirm it isn't just your network. Then ping infra.
