Open source software is code that is publicly available for anyone to read, use, modify, and distribute. Instead of being owned by a single company or person, it is built collaboratively by developers around the world — all working in the open.
Projects like Linux, React, Python, and VS Code are open source. The tools you use every day are built and maintained by communities of contributors, and you can be one of them. When you contribute to an open source project, your changes are reviewed by the project maintainers, and if accepted, become part of something used by thousands or millions of people.
GSSoC exists to make your first open source experience structured, mentored, and real. You work on genuine projects with real maintainers — not toy exercises. Your contributions ship to production.
Install Git on your machine and create a free GitHub account if you don't have one. Git is the version control system that tracks changes to code. GitHub is the platform where most open source projects live. Complete the GitHub beginner tutorial to learn the basics of repositories, commits, and branches.
For GSSoC, browse the official Projects page to find registered repositories. Look for projects that use a tech stack you know or want to learn. Read the README carefully — a good README tells you what the project does, how to set it up locally, and how to contribute.
Look for issues labelled 'good first issue' — these are specifically chosen by maintainers as appropriate for new contributors. Comment on the issue to express your interest and ask to be assigned before starting work. Do not submit a pull request on an unclaimed issue — it will likely be closed.
Fork the repository (creates your own copy on GitHub), then clone it to your machine. Follow the setup instructions in the README exactly. If something is unclear, ask in the project's Discord or issue thread before assuming. A working local setup is essential before writing any code.
Create a new branch with a descriptive name (e.g. fix/login-button-alignment or feature/add-dark-mode). Make your changes, test them locally, and commit with a clear message. A commit message should describe what changed and why — not just 'fixed stuff'.
Push your branch to your fork on GitHub and open a pull request against the original repository. Write a clear description: what you changed, why, how to test it, and any trade-offs. Add screenshots if you changed the UI. Then wait for maintainer feedback and respond promptly to any review comments.
No. Many contributions involve documentation fixes, test cases, translations, or UI improvements that do not require advanced programming skills. Start with good first issues and focus on projects using tools you already know.
You cannot break the original project. All changes you make are in your own fork until a maintainer reviews and merges them. The worst that can happen is your PR is closed. This is completely normal and expected for new contributors.
It depends on the project and maintainer. Some PRs are reviewed within hours, others take days. Be patient, respond to feedback promptly, and avoid sending follow-up messages within 24 hours of submitting. If there is no response after a week, a polite ping is appropriate.
You must contribute to projects that are registered in the GSSoC 2026 program. These projects are listed on the official Projects page. Contributions to non-registered projects do not count toward your leaderboard score.
Git is the tool — a version control system installed on your computer that tracks changes to code. GitHub is a website that hosts Git repositories online and adds collaboration features like pull requests, issues, and code review. Other platforms like GitLab and Bitbucket also host Git repositories.
