Can I reverse engineer GitHub?
An original rebuild of a GitHub-style MVP is rated 5/5 (very complex) and would take an estimated 12–18 months. Hardest engineering problem: Replicating GitHub’s distributed architecture, real-time collaboration features, and massive scale while maintaining security and performance is the single hardest engineering problem. Open-source projects such as GitLab, Gitea, Bitbucket are a practical starting point.
◈ How you might build it
Start with the smallest useful workflow: authentication, a focused developer tools experience, and persistent user data. Layer on collaboration, integrations, background processing, and production reliability as the product grows. The stack below is a suggested approach, not a verified description of GitHub's internals.
