How It Works

  • Apply

    Interested contributors propose a project to work on.

  • Code

    Accepted GSoC contributors spend the summer coding with guidance from a mentor.

  • Share

    Submit your code for the world to use!


Potential GSoC contributors contact the mentor organizations they want to work with and write a project proposal based on ideas the organization has suggested. Once accepted, GSoC contributors spend a few weeks becoming familiar with the community norms and codebase while determining expected milestones with their mentor for the summer. GSoC contributors then spend 12+ weeks coding on their projects.


Open source projects apply to be mentor organizations. Once accepted, organizations discuss possible ideas with contributors and choose the proposals they wish to mentor for the summer. They provide mentors to help guide each contributor through the program.


Community members and committers already active in the mentoring organizations can choose to mentor a contributor project. Mentors and GSoC contributors work together to determine appropriate goals for the program period. Mentor interaction is a vital part of the program.
