Mattermost Community

Hacktoberfest 2020 was Mattermost’s biggest Hacktoberfest ever

Hacktoberfest has become a tried-and-true tradition over the years, one that Mattermost has always been excited to be a part of. With 2020 being a year of surprises, twists, and turns, we expected nothing less from our current and future Community members when October arrived, and we were not disappointed.

Hacktoberfest 2020: More contributors and PRs than ever before

This year, we are proud to say we had over 150 contributors commit over 400 pull requests on all parts of the Mattermost ecosystem! This shows exponential growth since we began participating back in 2015. Take a look at the growth we’ve seen over the last six Hacktoberfests!

Some of the biggest contributions came in end-to-end tests written in areas with less than complete coverage, plugins and integrations, and, of course, documentation. Hacktoberfest 2020 definitely showed how important contributions beyond the code itself can be.

Notable pull requests from the Mattermost community

With over 3,000 users on the Mattermost Cloud workspace, it’s easy to see people were excited to participate and make Mattermost the best safe and secure communications tool in the world. Let’s take a look at some of the amazing pull requests from this Hacktoberfest.

Beyond Hacktoberfest: Contribute to the Mattermost all year long

We could not be more thrilled with the participation we’ve seen from our Community this Hacktoberfest. Of course, there is no need to limit participation to this event. As part of our dedication to open source, we are happy to accept PRs all year long! 

Feel free to explore the Mattermost repositories and find something to hack on or grab some Help Wanted tickets and improve the ecosystem we all know and love. If you have submitted something during Hacktoberfest that has not yet been merged, please know our team has marked everything as “hacktoberfest accepted” and is still working through pull requests.
We look forward to seeing your new PRs and can’t wait to see what the next Community tools get built for Mattermost. For more information about how you can get involved with the Mattermost open source project, check this out.
