Slack alternative: a practical guide to European team chat
Find a new home for team channels, everyday conversations and the knowledge your colleagues need to keep.
The right Slack alternative needs to work on an ordinary busy day: colleagues find the right channel, notifications reach them, and yesterday's decision is easy to search. Start with one team and a handful of real workflows before moving the whole organisation.
The shortlist below separates hosted services with verified European control from self-hosted software and other reviewed listings. Use it to compare options such as mssgs, Stackfield, Infomaniak kChat and Nextcloud Talk, then open the full directory for more services and their evidence.

Recreate your everyday work
Pilot a project channel, an incident update and a conversation with an external guest. Check your identity provider, bots and incoming webhooks individually. Keep a list of integrations that need a replacement or a manual step.
Check what your Slack export includes
Slack export coverage depends on your plan and permissions. Public-channel exports include messages and file links; access to private channels and direct messages has additional requirements. Verify coverage before planning an import. Slack export documentation →
Plan a clear switchover
Agree on channel names, owners and notification defaults during the pilot. Test the archive and any supported import, announce the switchover date, and tell colleagues where older discussions remain available. Assign ongoing administration to a named owner.
Questions
What is a good European Slack alternative?
Compare the verified hosted options below against your team's channels, search, calls and integrations. There is no single winner for every workflow; validate the shortlist with your own colleagues.
Can a Slack alternative import everything?
Do not assume a complete transfer. Test messages, users, threads and attachment access in the destination. Keep a readable archive of anything the importer cannot preserve.
Is self-hosted chat automatically hosted in Europe?
No. Your chosen server, backups and connected services determine the data path. Include patching, monitoring and recovery work when comparing self-hosting with a managed service.
