Launch video calls directly from Mattermost

We’re happy to announce our new integration with BigBlueButton, an open source web conferencing platform.

After installing the plugin, Mattermost users will be able to:

  • Invite colleagues to video and audio calls with a single click
  • Create team collaboration meetups in specific channels
  • Record sessions for later viewing
  • Search channels for recordings

Hacktoberfest was incredible

The fifth annual Hacktoberfest was a huge success.

According to DigitalOcean, over 46,000 open source enthusiasts submitted more than 400,000 pull requests to upwards of 105,000 open source projects.



Hacktoberfest was incredible for Mattermost, too. We received 83 pull requests from more than 30 contributors—including 29 people who hadn’t contributed to the project before.

Here are some highlights of what our community contributed:

Huge thanks to all of you and everyone else who participated as well.

Just because Hacktoberfest is over doesn’t mean you have to wait until next year to join in on the fun.

If you’re interested in contributing to the Mattermost open source project, read this to get started, check out our open issues on GitHub and stop by our contributors’ community channel to say hello.
