Hackathon - Luxembourg Internet Days 2025

NOVEMBER 18 & 19, LUXEMBOURG

THE CHALLENGE

Get ready to dive into the “Matrix meets Luxchat” Hackathon powered by the Ministry for Digitalisation and LU-CIX ASBL, in cooperation with Luxembourg House of Cybersecurity & Digital Learning Hub at the occasion of the Luxembourg Internet Days event.

Join the 20-40 developers expected to team up to supercharge Luxchat(4Gov) & Luxchat4Pro, the instant messaging solutions, based on the Matrix protocol, powering seamless communication and interactions for both public and private sectors in Luxembourg!

Over two days, Nov. 18 & 19, you’ll be able to brainstorm and code creative solutions (using Python) for additional services sticking to real-world challenges and integrate them within Luxchat, like:

Various kind of bots (AI chat, external services notifications, video games, …)
App improvements (Themes, built-in plugins, accessibilty improvements, …)
System solutions (better server ressource management, room activity analysis tools, automated deployment, …)
More will be communicated to the teams a few days before the event.

Streamlining (citizen) services,
Creating chatbots enabling service opportunity between private companies and customers,
Boosting engagement with providers, media or government platforms,
Creating service application of a specific business, e.g. real-time order tracking,
Using APIs to integrate Luxchat4Pro in your own IT infrastructure,
Interconnecting a AI-driven tools with a chatbot using Matrix APIs,
And more…

The main objective lies in integrating external services into the Luxchat ecosystem with the purpose of bettering these workflows.

As a multidisciplinary team, you will have 30 hours to craft work demos and 10 minutes to pitch your ideas in English in front of a jury composed of Matrix Experts.

This hackathon is your chance to show your creativity in this exciting challenge…and be rewarded for it!

It’s all about sparking innovation and making Luxembourg’s digital future more resilient, sovereign!
