info Overview

Mattermost is an open-source, self-hosted team messaging platform — a powerful alternative to Slack and Microsoft Teams that runs entirely on your own server. It gives your team channels, direct messages, threaded conversations, file sharing and search in a fast, familiar interface, with your conversations and files kept on infrastructure you control.

Beyond chat, Mattermost includes voice calls and screen sharing, deep integrations and webhooks, bots and slash commands, and Playbooks for repeatable workflows — all with no per-user cloud fees. Valebyte deploys the full stack (app plus database) for you: one click, automatic HTTPS, your team's data on your own server.

quiz Frequently Asked Questions

Is Mattermost a good self-hosted Slack alternative? expand_more

Yes. Mattermost offers the same channel-based messaging, threads, file sharing and integrations as Slack, but self-hosted on your own server with no per-user cloud fees and full data ownership.

Does it come with a database? expand_more

Yes. Valebyte deploys the complete stack — the Mattermost app together with its own PostgreSQL database — automatically, so there is nothing extra to set up.

How do I become the admin? expand_more

The first account you create on your new Mattermost instance automatically becomes the system administrator. There is no preset password — just visit your site and sign up.

How long does deployment take? expand_more

A few minutes. Valebyte pulls the app and database images, wires them together, issues an HTTPS certificate and starts them, then you create the first admin account.

Can my team use mobile and desktop apps? expand_more

Yes. Mattermost has official desktop apps for Windows, macOS and Linux and mobile apps for iOS and Android — they connect to your server URL.

Is our data private? expand_more

Yes. All messages, files and user accounts live on your own VPS and are never shared with a third party. You own the server and the data on it.
