Hacktoberfest 2021

Join Us For Hacktoberfest 2021

Another year, another Hacktoberfest; this year marks the 8th anniversary of Digital Ocean’s world-famous autumnal event. Hacktoberfest is a wonderful opportunity to bring all open source developers together, from newcomers to seasoned veterans, and we’re making Hacktoberfest 2021 our biggest event ever, with the most opportunities we’ve ever had to get involved in our community. 

With those opportunities come great swag! We’re supporting the effort by offering limited edition Mattermost stickers to everyone who makes one or more contributions to the Mattermost community during Hacktoberfest. Additionally, we’ll select top contributors in each participation category to receive a custom Mattermost mechanical keyboard. We’re also including our community in a new effort to provide financial support to the open source communities we rely on the most.

Translate Mattermost

Mattermost has been translated to dozens of languages, all thanks to our fantastic community of translators across the planet. No matter what languages you speak, there are opportunities to get involved in translating the Mattermost UI. In particular, we need help with Italian, Korean, German, Polish, Ukrainian, and Hindi translations, but any language listed as a work in progress is a great place to get involved.

Help Focalboard Get Ready for Primetime

Focalboard has achieved enormous growth over the last year, and we’re working hard to make it a more seamless component of the Mattermost experience. We’ve iterated very quickly on Focalboard to make its features more competitive with existing task management solutions. Today, we’ve reached a point where we can use help to write unit tests that improve Focalboard reliability.

This challenge is ideal for anyone who wants to expand their Go programming skills and get more familiar with a rapidly-growing code base. This challenge is also suitable for anyone new to the Mattermost community and wants to get more familiar with our code before jumping into more significant contributions.

Show Off Your Best Mattermost App

Mattermost Apps are lightweight, interactive add-ons that can be written in any language and run on any HTTP-compatible hosting service. Apps make it extremely easy to read or post messages, change the user interface, create interactive models, and modify just about everything else in the Mattermost experience.

We want to see your best Mattermost Apps and to get feedback about your experience building them. Create a new, unique App during October, and submit it as your Hacktoberfest contribution.

Submissions will be reviewed by our team and ranked according to two simple criteria:

  1. The ability to demonstrate a solution to an important uses case or common problem. Use images, gifs, and videos to show off your App.
  2. Clear documentation that shows how to install, configure, and use your App; this is the only way we can fully evaluate your contribution. We recommend following the Standard Readme Format.

Learn more about building Mattermost Apps; once you’re ready to submit your app, fill out this form.

Community Writing Program

We’re launching a new program for developers worldwide to get paid to write content about modern software development tools, services, and technologies. Share software development productivity hacks, write about your favorite app development framework, tell stories about building and deploying modern software, or share any other unique insight you have about technology. We’ll pay you to publish it on our blog.

Contribute to the community writing program.

QA Testing

Work closely with experts from our Quality Assurance (QA) team to test new Mattermost. You’ll spend time installing and running the latest builds of Mattermost and making sure everything works as expected. This is an excellent opportunity for non-developers to participate in a software development project and get credit for participating in Hacktoberfest.

Other Ways to Get Involved

Our Hacktoberfest handbook page has all the details about every possible way to get involved with us.

Issues labeled Good First Issue are great for newcomers; make sure you follow our contribution guidelines. Any issues labeled Help Wanted are also up for grabs. However, some of them may require fairly deep technical familiarity. We’re here to help you along the way; reach out to our maintainers early in GitHub and our community chat server to ask questions and get guidance.
