Mattermost Hosting
Team chat like Slack, but on your own server — channels, threads, search and integrations, with no per-user fees and unlimited message history.
What is Mattermost?
Mattermost is an open-source team communication platform: channels per project and department, direct messages, threads, emoji reactions, file sharing and powerful search across the entire history. Desktop apps exist for every operating system, plus mobile apps for iOS and Android. It is used by engineering teams, banks and institutions worldwide.
What does Slack really cost you?
Slack bills per user every month and hides your history behind a paid tier — while your data sits in someone else's cloud. With managed Mattermost you pay a flat price for the whole team, history is unlimited forever, and the communication lives on your server in Europe. For a 20-person team the difference is hundreds of euros a month.
Built for technical teams
Webhooks, slash commands and ready-made integrations with GitLab, Gitea, Jira and n8n make Mattermost the hub of your DevOps workflow. We keep the instance updated, backed up and monitored around the clock — you just talk to your team.

Frequently asked questions
