European team communication tools

European alternatives to Slack. Keep your team conversations off US servers.

Team chat apps are where a company talks all day. Every message, file, and decision passes through them. European tools keep that history under EU law. Wire and Element use end-to-end encryption, so the content stays private. Element is even used by several European governments and armed forces. Your team's daily conversation stays on European servers instead of a US one.
