Is this right for my business?
This is a great fit if...
A real scenario
Imagine you run a 20-person company. You pay €145/mo for Slack Pro (20 users × €7.25) and your team chats are stored on US servers you do not control.
As your team grows, your Slack bill grows too — €362/mo for 50 users.
With Mattermost on an Oktoja server for €29/mo, you pay the same whether you have 5 or 500 team members. All messages stay on your EU server. No per-user fees. Ever.
What is Mattermost?
Mattermost is an open-source team communication platform. Create channels for projects and teams, send direct messages, share files, and host video calls — all on your own server.
It gives you the features of Slack and Microsoft Teams, but you own the infrastructure, control the data, and never pay per-user licensing fees.
What it Replaces
Slack Pro: €7.25 per user per month
Microsoft Teams: €4.20 per user per month
💰 With Mattermost on your own server, no per-user fees ever. Unlimited team members.
