If you want to take part in this year's Webfest, please register here. Only persons with a CERN badge can take part (staff, users, students (administrative, summer, technical)).


Submitting your ideas
Anyone participating can pitch a project; pitches consist of short (less-than-five-minute) presentations. Participants are encouraged to submit their project ideas, using a tool on the Webfest website in advance, for the best chance of forming a well-defined team.

  • Maximum team size: 7


Project ideas will be presented at a kick-off event on Friday, 26 July, from 4.00 p.m. to 6.00 p.m. Participants will organise themselves into teams to work on the most exciting pitches. The kick-off event will also introduce a range of tools for web development, creating online educational tools and contributing to science online.

  • Pitching time in the kick-off session: 3 minutes
  • Preformation of teams and working on projects before the kick-off is generally allowed. If this applies, the judges have to be informed and they will take this into consideration when judging the project.


Where will the participants work?
Teams will work on their Webfest projects primarily in CERN Restaurant 1. As the location is an open-space environment, there will be plenty of opportunity for interaction, both between participants and with the various technical experts (mentors) taking part in the event. CERN openlab will provide free meal tickets for participants.


What tools will the participants use?
Going by the open-source spirit, we encourage everyone to open source whatever they build in the Webfest using open licenses like MIT(link is external)Apache(link is external)GPLv2, GPLv3(link is external) or Creative Commons(link is external), etc. You own all the code you write for the Webfest, but you should be comfortable in letting the judges/organizing team assess the whole of your code.


Presentations and winners
The event will wrap up on Sunday, 28 July at 4.00 p.m., with a judging panel reviewing the results (based on five-minute ‘lightning talk’ presentations by the teams) and awarding prizes.

  • Time to present your ideas to the judges: 5 minutes presentation + 2 minutes Q&A
  • Judging criteria : 
    • Innovation
      How innovative the technical solution is
      (1 = no innovation, 5 = very innovative)
    • Presentation
      Creativity on the project presentation 
      (1 = bad presentation, 5 = great presentation)
    •  Impact
      Potential impact in a real world application 
      (1 = no impact, 5 = great impact)
