Mattermost is a fully flexible and customizable business messaging app. It’s open source and completely free, so you don’t have to pay based on the number of workers you use like you do with alternatives like Slack or Microsoft Teams. Of course, to use Mattermost, you need to host the Mattermost server on your own server.

We host the servers and communications, but Mattermost encrypts all traffic. Thanks to that, I can talk about what I’m saying internally without anyone knowing. Mattermost lets you create channels to centralize communication and conversations with your team. You can also create meetings and have private conversations with each worker.

The interface is similar to other applications on the market, especially reminiscent of Slack. Each user has a name and photo and can reply directly to groups or specific messages. Of course, you can’t miss the reactions with emojis.

From Mattermost, you can also manage your projects and integrate other work platforms such as Google Drive, Dropbox, Trello, and Jira. You can automate some tasks, create checklists, etc. All this to simplify your workflow.

So if you want a robust, secure and free messaging application, don’t hesitate and download Mattermost.
