In detail
A chat server per company
Slack runs only in Slack’s cloud. In Xenaxio every company gets its own chat server for Rooms – in Germany in Xenaxio Cloud, or on your own servers. Channels, direct messages, threads, mentions, reactions, files and search work as in Slack, with push notifications on computer and phone and calls right in a channel or direct message.
Talking to other companies
Shared channels with partners run over the open Matrix standard: the other company joins from its own Matrix server, not from an account on yours. Your administrator decides whether that is allowed and with which servers. For teams that only want the chat, Rooms is also available as a product of its own, XenRooms.
Chat next to mail, calendar and the AI
Because Rooms sits next to email and calendar, the assistant can answer “What did I miss in #project-north?” and combine chat with mail – if your administrator allows the AI to read the team chat. In Rooms the AI only reads and searches; it never writes there. Slack has a larger app directory; Xenaxio connects through webhooks and its MCP connector.
