Affordable Open Source Alternative, But Lacks UX Polish

I like that Mattermost is open source. I also value that it's free to use if you set up your own server.

Secure, Customizable Self-Hosted Messaging That Boosts Team Collaboration

What I like most about Mattermost is its strong focus on security and customization. The option to self-host gives us complete control over our data, which is a major advantage compared to other messaging platforms. On top of that, the interface is clean, performance has been reliable, and the available integrations make team communication and collaboration noticeably more efficient.

Easy to Use, Well-Organized Chat with Great Search and Pinning

It’s easy to use and it’s organized well unlike other work chat options like Slack. It’s easy to search and find messages or documents and you can pin information for later use as well.
