Let’s Hack!

Inspired by the great success of 2022, we are planning the 6th edition of CloudFest Hackathon based on what worked best for you. We couldn’t be more thrilled to welcome developers and other web professionals from across the cloud industry to Europa-Park in Rust to hack and have fun by solving some real-world problems.

Again, we’ll be focussing on creating friendly competition between projects, social interaction and promising networking opportunities for our hackers.

Here’s how it went down during the last edition

Who Should Attend?

Team up, bring an idea into life, set new milestones to existing projects and release your Hackathon results into the wild!
You will be working with other passionate hackers who are equally excited to make a positive contribution in the #OSS world (starting with GitHub, of course).

Results of the Hackathon will also be showcased to the 7,000+ attendees of CloudFest. Harness the power of open source and make some magic happen!

Attendee Profile

The event is mainly targeted, but not exclusively limited, at Web Developers, Software Engineers, Sys-Admins, Frontend & UX-Designers with the following skills

  • Knowledge in one or more programming languages of your choice, e.g. PHP, JavaScript, Bash, Go, Python
  • Basic understanding of the technical basics in the cloud/hosting industry (common services, network protocols, web services etc.)
  • Experience with Git as version control system
  • Anybody interested in helping to make the web a better place!

We are actively striving for a diverse and productive group of participants with different backgrounds, skills, and knowledge to bring about big and positive changes together in the open-source world.

That’s why we also welcome applications from system & infrastructure engineers (DevOps), data scientists, sysadmins, designers, marketers and other web professionals with interest in the Cloud & Hosting industry for our projects.

Diversity and Inclusion

One of the top priorities of the CloudFest Hackathon is to encourage diversity and create a welcoming and safe atmosphere for all. In 2023, we want to further increase our efforts in this regard. This is why we will team up with experts and representatives of underrepresented groups in tech.

We also want to ensure we can meet the needs of our attendees when it comes to dietary requirements and accessibility, in general. That’s why we include related questions in our application process at a later stage.

We expect all our attendees to be considerate, respectful, and collaborative towards each other and to refrain from demeaning, discriminatory, or harassing behavior and speech.

Feel free to reach out to us for questions and suggestions:

Projects for 2023

The 2022 Hackathon saw a global gathering of web professionals working together on eight different and exciting projects. Again, projects for 2023 will all be not-for-profit, interoperable, and – of course – open-source. Ideally, they are related to the hosting industry, hackable and beneficial for different actors of the industry present during CloudFest. To encourage friendly competition between the projects, there will be a jury to determine a winner in different categories.
