Inspire. Have Fun. Repeat.
Voxxed Days CERN returns for its sixth edition on Friday, 5 March 2027, at the CERN Science Gateway. The conference offers you a rare chance to visit one of the world's most respected centres of scientific research, meet fellow developers, and hear from some of the most respected speakers of the sector. Organised together with CERN, Exteso and the Swiss developer communities, it is a single day of production-grade talks and honest hallway conversations at a truly iconic location.
Java, JavaScript, AI models or infrastructure: if you build software, come build it where humanity studies the universe.
2026 Edition Highlights
Sponsors
Sponsoring puts your brand in front of hundreds of engineers, architects and tech leads from the Geneva region and far beyond, the people who pick the tools their companies buy.
Bring Your Brand to CERN
