Team Chat Without the Slack Price Tag.

Is this right for my business?

This is a great fit if...

You have a team of 2–50 people
You want to reduce monthly software costs
You care about data privacy and GDPR
You want EU-hosted, self-owned solutions
You are tired of per-user licensing fees
You want everything set up for you

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.

💰A 20-person team saves €116/mo — that is €1,392 per year — with full data ownership included.

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.
