About

The ‘Webfest’ — CERN’s annual hackathon based on open web technologies — will take place on the weekend of 21-22 August (with a pitch session on Friday 20 August, and winners announced on Monday 23 August). The hackathon is open to all and will again be held online 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 ‘science, society, sustainability’. We encourage projects that support the UN’s Sustainable Development Goals (SDGs). Projects that relate to the five SDGs to which CERN de facto contributes, are of particular interest. These SDGs are as follows:

 

3. Good health and well-being
4. Quality education
9. Industry, innovation, and infrastructure
16. Peace, justice and strong institutions
17. Partnerships for the goals


Projects for facilitating online science collaboration — thus reducing the need for frequent international travel — are also strongly encouraged. This picks up on the theme of last year’s Webfest and is in line with SDG:

13. Climate action

The goal is for the CERN Webfest to serve as an exemplar for how people can come together virtually — from all corners of the globe — to collaborate successfully, without the need for long-distance travel with a large CO2 footprint. Other environment-focused projects are encouraged at the Webfest too, in support of CERN’s Year of Environmental Awareness.

Participants will work in teams, focusing on specific ideas to create tools to support the changing ways in which we collaborate to help improve the world. During the course of the Webfest, participants will learn new skills and methods from each other and from experienced mentors. The participants will be able to use and to share those skills and methods in their future professional life.

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

If you have an idea for a project or if you want to contribute to another participant’s project you are interested in, don’t hesitate to register for this year’s Webfest! This is a great opportunity to spend a weekend being creative and social, with a bunch of passionate fellow students and scientists from all over the world. The best projects will be awarded with prizes. 

Post your ideas and proposals online on our website, and get in touch with other like-minded participants who may want to help you out with the project. You can contribute as a mentor or helper too: http://cern.ch/go/fnP6.

Join us via the web — born at CERN — to help improve our world. 

*Registration closes at 23:59 CEST on Tuesday 17 August.
