Your team’s conversations, in a room you own.

Cenacle is open-source team chat with its own sign-in server. You install it on your servers; messages, files and accounts stay there.

Arrives with version 1.0. We are finishing the web and desktop apps.

Runs on your servers: One Docker Compose stack or a Helm chart. Works without internet access.
Open source: GNU AGPL 3.0. Read it, change it and run it.
One sign-in: Cenacle ID: passwords with two-step verification, passkeys, LDAP, SAML or OpenID Connect.
Nothing reports back: No telemetry, no tracking, no outside services. Even the fonts ship with it.
