Mattermost Self-Hosted: Skip the Setup, Keep Full Control
Deploy your own open-source team chat platform in 3 minutes. Transparent pricing. GDPR-compliant EU data residency. Zero monthly ops overhead. Unlimited users. No per-seat charges.
Why Choose Opsily for Mattermost Hosting
The complete self-hosted Mattermost setup without the self-hosted headaches.
Self-Hosted Pricing Without Per-User Charges
Slack costs €6.75 to €15 per user every month. Mattermost on Opsily costs one flat rate for unlimited users, teams, and message retention. Your 50-person team pays the same as your 500-person team. No surprise seat billing when you scale.
GDPR-Compliant EU Data Residency
Your Mattermost instance stays in EU infrastructure you control. No multi-tenant risk. No hyperscaler lock-in. Compliant with GDPR, HIPAA, and DoD STIG requirements. Used by Samsung, Uber, and the U.S. Department of Defense.
Zero Ops Overhead
DIY self-hosting costs €24/month in server rent plus 1 to 2 hours a month for patches, SMTP setup, backup verification, and database tuning. Opsily handles all of it: daily automated backups, one-click updates, SSL renewal, performance monitoring, and scaling. Your team stays focused.
Built for teams who need reliability
DIY vs. Managed: What Self-Hosting Really Costs
Mattermost on a VPS sounds cheap until you factor in your time.
DIY costs based on public VPS pricing and standard setup time. Opsily includes infrastructure, backups, monitoring, and updates.
Why Teams Move from Slack to Mattermost
Slack's 90-day history wall costs teams real money and decisions. Mattermost doesn't.
Open-Source Means No Lock-In
Mattermost runs on your infrastructure. If you ever decide to leave Opsily, you own your data and your instance. Export everything. Move to another provider. Run it yourself. That option costs you nothing, and it exists forever.
Slack doesn't offer that choice. Teams trapped in Slack's 90-day history wall report losing client decisions, onboarding records, and institutional knowledge. Mattermost's self-hosted model means unlimited history, controlled by you.
GDPR and Data Sovereignty
EU enterprises and regulated teams (finance, healthcare, legal) are moving to Mattermost because Slack's data residency guarantees depend on Azure or AWS, which fall under the Cloud Act. Mattermost on Opsily stays in EU data centers. Your data never leaves EU infrastructure. Full transparency. Full control.
39,000 Stars on GitHub. Used at Scale.
Mattermost has 23,228 commits from an active community. GitLab ships it as the default chat platform. Uber runs 70,000 concurrent connections through a single Mattermost cluster. The U.S. Department of Defense uses it for classified communications. Samsung and Wargaming run Mattermost at scale. This is not a startup project.
