Build with the API →Federation
Share a channel, not your organisation.
Two administrators exchange a one-time key and compare a fingerprint. Once both approve, either side can share a channel with precise permissions. People remain on their own server and use their own accounts.
Every shared channel has one owning server, giving its messages a clear order and its files one permission model. It is deliberately small, and that is what keeps federation comprehensible.
