CloudFest Hackathon 2026: record-breaking year and new era of collaboration

#Introduction to CloudFest Hackathon 2026

The open source community eagerly anticipates the ninth edition of CloudFest Hackathon, taking place in late March 2026. This edition promises to be the most record-breaking in the event’s history, both in terms of the number of submitted projects and a new, expanded schedule. Organizers have prepared a series of changes to make this event even more valuable for participants and the entire open source ecosystem.

Carole Olinger, Head of CloudFest Hackathon, shared with the community information about how the event’s enormous success has created new organizational challenges. With only about 110 spots available for participants and only 10 projects to choose from, selection is incredibly difficult. “It breaks our heart,” Olinger emphasized, noting that even hackathon veterans sometimes don’t make the cut.

#New Schedule - Three Full Days to Build

One of the most significant changes in the 2026 edition is a completely redesigned schedule. Unlike previous years, when teams had limited time to complete their projects, this year’s hackathon offers three full days for building. This change was introduced in response to feedback from participants who complained about insufficient time to polish their solutions in previous editions.

The new schedule gives teams greater flexibility in planning and executing their projects. Instead of racing against the clock, participants can focus on the quality of their code and the innovativeness of their solutions. Organizers noted that projects from previous editions were often incomplete or required significant fixes after the hackathon. The new schedule aims to change this.

#Why Three Days Matter

The decision to extend the hackathon to three days was based on several factors:

1. Quality Improvement: More time allows teams to produce higher-quality, more complete projects.

2. Reduced Stress: Participants don’t have to rush, leading to better mental health during the event.

3. Learning Opportunity: With more time, participants can learn new technologies and techniques.

4. Better Networking: Additional time for informal conversations and relationship building.

5. Future-Proofing: The extended schedule sets a new standard for hackathons.

#Historical Context of CloudFest Hackathon

CloudFest Hackathon began in 2017 as a natural extension of the CloudFest conference. The first edition attracted just 30 participants, but quickly gained popularity. Each year, the number of applicants grew, and with it, the quality and innovation of projects.

Over eight years, the hackathon has generated many significant open source projects now used by thousands of developers worldwide. Projects like WP GraphQL, Faust.js, and Calypso originated from initiatives related to CloudFest.

#Why CloudFest Matters

#Thematic Range of Projects

This year’s projects cover a wide thematic range, from accessibility tools to infrastructure experiments and artificial intelligence. One of the more interesting projects is an attempt to extend the FAIR package distribution protocol to the TYPO3 ecosystem. FAIR (Fully Automated Interoperable Repository) is a project aiming to create a decentralized package distribution system for PHP, similar to what Cargo is for Rust or npm for JavaScript.

The project to extend FAIR to TYPO3 is particularly interesting because it shows how ideas from one ecosystem can be adapted to others. If the experiment succeeds, it could open new possibilities for PHP developers throughout Europe.

#Return of Anne-Mieke Bovelett

This year’s edition also sees the return of a well-known figure in the hackathon world. Anne-Mieke Bovelett, a two-time CloudFest Hackathon winner, has submitted her project once again. The question on everyone’s mind is: will she win for the third time?

Bovelett has already proven her worth in previous editions, delivering innovative solutions that exceeded the expectations of organizers and the community. Her return adds an extra element of excitement to this year’s edition, and the community eagerly awaits the results.

#Innovative AI Art Project by Alain Schlesser

#AI-Generated Art Concept

One of the most innovative and unconventional projects of this year’s hackathon is the work of Alain Schlesser, an experienced project mentor. Schlesser created an AI art project that will capture the atmosphere of the event in real time.

Schlesser’s system will draw data from various sources: weather, sound, social media activity, and even a webcam. Based on this data, an AI algorithm will generate an evolving digital artwork that will change as the event progresses.

#Significance for the Community

This project is an example of the creative approach to technology that characterizes the open source community. Instead of focusing solely on “serious” technical projects, Schlesser shows that a hackathon can also be a space for experimenting with more artistic and interactive applications of technology.

The resulting project will be a fascinating visual record of the energy and atmosphere of CloudFest Hackathon 2026. The build itself - a system that collects and processes data from multiple sources in real time - is technically demanding and yields valuable experience for participants.
