The Mattermost server repo surpasses 20,000 stars on GitHub

In March 2021, the Mattermost server repository officially surpassed 20,000 stars on GitHub, and we couldn’t be more excited! 

Huge thanks to our community for their incredible support of the Mattermost open source project and their belief in the power of secure workplace messaging solutions built for developers by developers.

Some history and some highlights

The Mattermost project has grown considerably since it launched on June 28, 2015.

Over the years, our ever-growing community has invented and contributed hundreds of impressive features. To highlight our contributors’ achievements, we vote on a Most Valued Professional each month.

Thanks to our community’s help, Mattermost now ships in 18 different languages, and many additional languages are in progress. (If you’re interested in helping out with Mattermost localization efforts, check this out.)
