Open Source Jam is an event aimed at promoting the culture of contributing to free and open-source software, and building community.

participate, no matter if you have never made a contribution before, you will have the help of your team and specialized mentors.

prize of €1200 per team
complete the form, it is very important that you confirm your participation by email
make an impact
you collaborate with both large and small projects. The former because we use their code every day and the latter because they have fewer contributors, the impact can be greater.
have fun
this is not a typical competition, that's why we work in teams. We want to bring together people who love code as much as we do, the goal is to get to know each other and enjoy doing what we love.
move forward
Contributions speak very well of you, they always serve you to promote yourself or open new doors. Do the tasks with the quality they deserve and if it's your first time, you will surely want to repeat.

•Frequently asked questions
Can I make more than one contribution?
Yes, organize yourself well with the team.
Can I offer a contribution that I have already made?
It is strongly requested to create new content for the event; sending old or already finished contributions doesn't make sense.
Can I make changes during the deliberation period?
you can't improve it, it's not allowed to make changes outside the deadline.
Can we register as a group?
Yes, although each member must register separately. Choose a name for your team and at the time of registration, each person must write it in the form.
Why will there be a prize?
Because most open source contributions are unrewarded and this is our way of supporting it.
Who owns the contributions?
The software generated is free. The contribution will be under the name of the person who uploads it.

celebramos la 3ra edición de open source jam del 16 al 23 de junio en las oficinas de google madrid. una semana donde ampliamos la comunidad en una tercera parte y elevamos las contribuciones al código abierto.
hubo un equipo ganador el equipo de jk formado por javier ríos urbano y kemil beltre; aunque la creatividad y la determinación de quienes participaron nos dejó con la boca abierta.
