Mattermost Pricing Self-Hosted: Why Your Costs Are Higher Than You Think
Mattermost Team Edition is free. The software costs nothing. But self-hosting typically runs €5,000-€6,000 per month for a 50-person team when you add infrastructure, DevOps labor, and compliance work. Here's what you actually pay.
Why Self-Hosted Mattermost Costs More Than You'd Guess
The software is free. But running Mattermost in production requires three things most teams underestimate.
Infrastructure
A production Mattermost server needs a dedicated cloud VM, managed PostgreSQL, and object storage for files. AWS, DigitalOcean, Hetzner—all cost money. Expect €50-€500 per month depending on your provider and team size.
DevOps Labor
PostgreSQL tuning, connection pooling, SMTP relay setup (SPF/DKIM/DMARC), SSL certificate renewal, backup verification. This is the job no one volunteers for. A DevOps engineer in Europe costs roughly €4,200 per month. At 50 hours per month at €84/hour, this is your largest hidden cost.
Compliance Work
If your company is GDPR-regulated, you need documentation, audit readiness, and legal holds. Depending on your industry, this can add €500-€1,000+ per month. Healthcare, finance, and government teams pay even more.
The Total
For a 50-person team:
- Software: €0
- Cloud infrastructure: €200-€500/month
- DevOps labor: €4,200/month
- Compliance: €500-€1,000/month
- Total: €4,900-€5,700/month
Add Mattermost Professional tier ($10 per user per month) and you're at €5,400-€5,900/month.
Annualized, that's €59,000-€68,000 per year. For a 200-person team, self-hosting costs €47,000-€80,000 annually when you account for scaling infrastructure and additional DevOps overhead.
The Cost Breakdown: DIY Self-Hosting vs Managed
What you actually pay when you run Mattermost yourself vs. letting Opsily handle it.
DIY costs assume 50 hours DevOps labor/month at €84/hour market rate. Infrastructure varies by cloud provider; estimates based on AWS/DigitalOcean pricing.
How Mattermost Compares to Slack and Teams
Many teams compare self-hosted Mattermost to SaaS chat platforms. The numbers are striking.
| Platform | Entry Tier | Cost Per User/Month | Annual Cost (50 Users) | Scaling Model |
|---|---|---|---|---|
| Slack Pro | Pro | €7.25-€8.75 | €4,350-€5,250 | Per-user (scales with headcount) |
| Microsoft Teams | Essentials | €4 | €2,400 | Per-user (scales with headcount) |
| Mattermost Self-Hosted | Free (Team Edition) | €0 software + labor | €59,000-€68,000 | Flat software cost + hidden labor |
| Mattermost Managed (Opsily) | All plans | Flat rate | Predictable | No per-user scaling |
What This Means
Slack looks cheap at €7.25/user until your team grows. At 50 users, you're paying €4,350-€5,250 per year. At 200 users, that's €17,400-€21,000 per year. Mattermost Professional self-hosted looks better on paper (free software) until you add labor.
Opsily's flat-rate model eliminates per-user scaling entirely. Add 100 new employees: the hosting cost stays the same. This is Mattermost's core advantage, and it only works if you're not drowning in DevOps overhead.

Everything you need to know about Mattermost costs and Opsily's managed hosting model.
Yes, with Opsily managed hosting. Your bill is flat per month. Add 50 users tomorrow and your bill doesn't change, as long as you stay within your tier's user capacity. With Slack or Mattermost per-user billing, each new hire triggers cost increases. With managed flat-rate hosting, pricing is predictable and decoupled from headcount. This is why mid-market teams (50-500 people) choose managed hosting: you can hire and grow freely without watching budget increases.
