Held 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 help people engage with CERN’s research, physics, or even science in general. In previous versions of the Webfest, participants have worked on a wide range of exciting projects: from physics-themed video games to mobile-phone cosmic-ray detectors, and from skills-sharing platforms to tools for translating sign language to text.

The Webfest is completely free to attend - there are no registration or other fees.

Yes, you are allowed to use third party libraries, but you are not allowed to use any paid libraries or WebAPIs which are trial versions and will work only for a limited period of time. And we  encourage everyone to use open source solutions to implement their ideas, irrespective of the licensing they choose for the final product.

You own all the code you write for the Webfest. However, going by the open-source spirit, we encourage everyone to publicly provide (open source) whatever they build in the Webfest using open licenses like MIT, Apache, GPLv2, GPLv3 or Creative Commons, etc.

We aim for the Webfest to be as global and diverse as possible. Within the teams participants can work in any national language they prefer. However, the moderation, pitching and presentation sessions will all be held in English, so you will need to understand the language, or have someone at your side who can help you with the English.

Yes! There are prizes to be won!

4.  Come at 16:00 to building 40 on Friday 21st July for the opening session of the Webfest. We will start with an introductory session, project ideas will be presented at the Kick-off Session on the Friday of the Webfest weekend. Participants will organise themselves into teams to work on the most exciting pitches.

If you would like to contribute to the event as a mentor, please sign up here.

Part of the role of a mentor involves answering general questions from participants throughout the event, from July 21 until July 23.

The event will be held from Friday 21 July - Sunday 23 July. Kick-off session on 21st of July, 17h (building40-Salle Dirac); hacking day 22nd of July, all day (R1); judging session 23rd of July, 16h (building 40).

Yes, this year's theme is 'education, science, and research', i.e. how can CERN's technology be applied for the benefit of society to support education, science, and research. Find out more on about page.

Everyone with the CERN badge (staff, users, fellows, origins, students...) are welcome to join and contribute with their knowledge and skills. Having people with diverse professional backgrounds is incredibly helpful for developing interesting and relevant applications.
