Cloudfest hackathon 2023 recap

A Game-Changer for
Open-Source Tech!

April 7, 2023, by Carole Olinger, Head of CloudFest Hackathon

Close to 120 hackers from all over the world gathered at Europa-Park Rust, Europe’s biggest amusement park, for the CloudFest Hackathon 2023. Working on innovative and game-changing solutions to open-source tech challenges, this year’s event attracted the largest attendance yet, increasing last year’s ‘Greatest Hackathon Ever’ by almost 50%!
In a collaborative and dynamic environment, software engineers, developers, and web professionals had the unique opportunity to demonstrate their talents and develop new skills. The vibes were fantastic, as seen on social media hashtags #CFHack and #CFHack2023.

Let’s dive into the highlights of this year’s record-breaking CloudFest Hackathon, including the winning projects, our partners, and some epic photos.

Game-Changing Hackathon Projects

We are thrilled to showcase the eleven exceptional projects that emerged from the CloudFest Hackathon 2023, all of which have the potential to make a significant impact on the industry and the open web. From web applications to software tools, these projects represent the best and brightest ideas from the event’s talented participants.

The projects were selected based on a range of criteria, including innovation, impact, and technical complexity, and we are proud to have been the enabler of their development.

Results-Oriented Projects

To ensure that all the project teams had a clear and achievable vision for their work, we enlisted the help of two experienced hackersβ€” Lucas Radke (Automattic) and Alain Schlesser (XWP)β€”who worked closely with our project leads. Together, they provided guidance and support in refining project ideas and setting goals for the hackathon.
Their contributions were invaluable in helping our teams to stay on track and make the most of their time at #CFHack2023!
And now, without further ado, here are the game-changing projects from CloudFest Hackathon 2023 that you’ll be hearing more about in the coming months:

Project Leads: Daniel Bachhuber and Adam Zielinski, Automattic

Goals: The team wanted to bring the entire WordPress development environment into the browser using WordPress Playground.

Achievements: They shipped three very promising demos:

  • An in-browser IDE with support for mobile devices and offline via StackBlitz
    πŸ‘‰ demo 1
  • A tailored in-browser code editor and terminal that can be customized to specific app needs πŸ‘‰ demo 2
  • A VisualStudio code plugin that starts a WordPress server even if you don’t have PHP or MySQL installed πŸ‘‰ demo 3 & demo 4

What’s next? These projects continue being developed on GitHub in the WordPress Playground repository. In the coming months, these code editing experiences will be tried and tested during various workshops to prepare it for the general WordPress audience.

Project Leads: Leonidas Milosis and Diede Exterkate, Yoast

Goals: Start creating a plugin that recalibrates the frequency of external requests happening from WordPress sites, for environmental and performance reasons.

Achievements: The team wrote a plugin with a couple of ways to automatically reduce a WP site’s external requests, thus decreasing its carbon footprint. Furthermore, they created an API that website owners can use to reduce the site’s external requests even further, depending on each site’s needs and functionalities.

What’s next? Implementations will be improved in order for the plugin to be considered production-level. If widely adopted as a canonical plugin, this project can potentially affect global Internet energy consumption considerably.

Project Leads: Anton Akhtyamov, WebPros

Goals: Create a CLI utility to analyze the file structure of a web hosting server and identify the frameworks, and CMS used in the websites hosted on it.

Achievements: The team added the identification of multiple technologies and frameworks as well as to the following CMS: WordPress, Joomla!, Drupal, PrestaShop & TYPO3. They also created a sample integration of the utility to the Plesk web hosting panel – to show it’s possible to integrate into any software. It’s also possible to make it work as a CLI utility on UNIX servers.

What’s next? Integration into Plesk Panel to identify the technologies and provide reliable instruments for customers.

Hack for a Purpose: Friendly Competition at #CFHACK2023

At CloudFest Hackathon 2023, we wanted to do more than just recognize outstanding projects – we wanted to make a real impact. That’s why we partnered with the Groundbreaker Talents initiative, a program that funds scholarships for vocational training centers in Uganda specializing in development and IT education.

Thanks to the incredible contributions of our attendees and the unwavering support of our partners and the open-source communities, we were able to raise €3,500 for this worthy cause. We’re thrilled to announce that World Hosting Days GmbH has added another €1,500, bringing our total donation to €5,000β€”enough to fund a full scholarship for a future female developer in Uganda.

By supporting Groundbreaker Talents, we aim to help create a sustainable livelihood for young developers in Uganda, while also contributing to a better, and more diverse open web. We’re proud to have played a part in this effort and can’t wait to invite the scholarship recipient to join us at CloudFest Hackathon 2024!
