Team Chat Platform Self-Hosted: Mattermost for Enterprise Teams
An open-source chat platform built for privacy-conscious enterprises. Own your data. GDPR compliant. Unlimited message history. 87% cheaper than Slack for a team of 10. Deploy in minutes.
Why Choose Managed Mattermost
The self-hosted chat platform that saves money, keeps your data, and integrates with everything you use.
€9/mo Flat Rate (vs €150/mo Slack Business+)
A 10-person team on Slack Business+ costs €150/mo. On Danian's managed Mattermost, the same team costs €9/mo flat. That is €1,692 in annual savings. Slack charges per user. Mattermost does not.
Full Data Control and GDPR Compliance
Your data stays in the region you choose. Danian offers 21 data centers across EU, US, and Asia-Pacific. No forced updates. Configurable retention. Legal hold support. No vendor lock-in.
300+ Integrations, Including Jira and GitHub
Native support for Jira, GitHub, GitLab, Jenkins, PagerDuty, Zoom, and Slack. Incoming and outgoing webhooks. Slash commands. REST API for custom bots and workflows.
Built for teams who need reliability
Teams Are Moving Away From Slack
Slack Free plan deletes messages after 90 days. Pro tier costs €6.75/user/month. Business+ costs €15/user/month. A 10-person team on Business+ spends €1,800 per year. Your messages, workflows, and integrations belong to Slack. You cannot migrate channels easily. You cannot control where data lives.
Mattermost: Data, Cost, and Control
Mattermost is an open-source, self-hosted team chat platform for enterprises that refuse vendor lock-in. It runs on your infrastructure or via a managed host. Every message is yours. Every integration is yours. You choose when to update. You choose where data lives.
On Danian's managed hosting, a team of 10 pays €9/mo flat. No per-user fee. No annual commitment. Unlimited users (Team Edition soft-caps at 250; upgrade to Mattermost Enterprise scales to 50K+ concurrent). Backups, monitoring, SSL, 24/7 support, and 99.9% SLA all included.
For organizations that cannot afford Slack's per-user model or refuse to let data live in Slack's US infrastructure, Mattermost is the answer.
