Google Summer of Code is a global program focused on bringing more student developers into open source software development. Students work with an open-source organization on a 3-month programming project during their break from school.
Google awards stipends to students who successfully complete a free and open-source software coding project during the summer. The program is open to university students aged 18 or over. The amount of the stipend depends on the purchasing power parity of the country where the student's university is located. Project ideas are listed by host organizations involved in open-source software development, though students can also propose their own project ideas.
