The ‘Webfest’ — CERN’s annual hackathon based on open web technologies — will take place online across July and August (with an introduction session on Friday 8 July and the winners announced on Wednesday 31 August). The Webfest will be held online again this year, meaning that people from anywhere in the world can take part.

Run each year since 2012, the Webfest brings together bright minds to work on creative projects. Participants work in small teams, often designing web and mobile applications that can be of benefit to society. 

CERN’s online Webfest isn’t just for those that can code: anyone with an idea, a challenge, or other skills is welcome to take part.

The theme for this year’s event is climate action and sustainability. Signifying the 10th anniversary of the CERN Webfest, this year's event will be held over July and August, allowing students to work on and develop their projects over a longer time period.

This year, instead of pitching projects, students will have the opportunity to work collaboratively on challenges relating to themes of climate action.

Participants will work in teams on solutions to these challenges, and learning new skills and methods from each other, and from experienced mentors. Following the Webfest, participants will be able to use and expand on these skills in their future careers.

Take a look at this short tour of the very first Webfest at CERN:

*Registration closes on Tuesday 5 July
