What is Google Summer of Code?
Google Summer of Code is a global, online program funded by Google that supports students and beginner contributors in working on open-source software projects. Participants are selected to contribute to approved open-source organisations under the guidance of experienced mentors.
The GSoc program was created to encourage new contributors to enter open-source communities and to help open-source projects grow with structured, mentor-supported contributions.
GSoC is not a traditional corporate internship at Google. Contributors do not work as Google employees. Instead, they work remotely with open-source organisations that are selected for the program.
Each selected contributor:
- Submits a project proposal aligned with an organisation’s idea list
- Works with assigned mentor(s)
- Completes a defined coding project during the official coding period
- Undergoes periodic evaluations
- Receives a stipend upon successful completion
Projects vary in scope and duration. Depending on the size selected, contributors may work for approximately 10 to 22 weeks.
The core objective of Google Summer of Code is to:
- Introduce new developers to open-source software development
- Encourage long-term participation in open-source communities
- Provide hands-on experience in collaborative software engineering
- Help organisations build sustainable contributor pipelines
Over the years, GSoC has become one of the most recognised open-source internship programs globally, valued for its structured mentorship model and real production-level contributions.

Once selected, contributors move through the following stages:
1. Community Bonding Period
This period begins after contributor announcements. During this phase, you:
- Interact with your mentor(s)
- Refine project goals and milestones
- Set up development environments
- Understand the organisation’s workflow and codebase
No major coding deliverables are expected during this stage. The focus is preparation and alignment.
2. Coding Period
The official coding period is when contributors actively work on their approved project. GSoC supports different project sizes, which determine the expected duration.
| Project Size | Estimated Duration |
|---|---|
| Medium Project | Approximately 12 weeks |
| Large Project | Approximately 22 weeks |
Contributors are expected to:
- Follow agreed milestones
- Submit code regularly
- Communicate progress updates
- Respond to mentor feedback
3. Evaluations
During the coding period, contributors must pass required evaluations conducted by mentors. Evaluations assess:
- Project progress
- Code quality
- Communication consistency
- Milestone completion
Successful completion of evaluations is necessary to continue in the program and receive the stipend.
The structured format ensures accountability, technical growth, and measurable project outcomes. Contributors are treated as active open-source developers, not short-term trainees.
