GitHub has alternatives, but no replacement

Codeberg, a Git code hosting platform, recently decided to prohibit projects that mostly consist of generative-AI-written code, prompting concern and extensive discussion. The decision does not surprise me, as Codeberg presents itself as a mission-driven alternative to GitHub, not neutral infrastructure. However, the disappointment in its response reveals a bigger gap in the open-source space.

While there are many places to host Git repositories, few host open-source communities. GitHub provides projects with shared identities, habits, and paths to discovery, which none of the alternatives has reproduced at a similar scale.

GitHub's social layer, including identities, conventions, and discovery methods, is crucial for attracting and retaining contributors. Self-hosting Git does not provide the same social experience, as users must create new accounts, learn new workflows, and follow different conventions. The discovery aspect of GitHub is also lacking in most alternatives. While some projects, like Codeberg and SourceHut, offer decentralized or mission-driven alternatives, they struggle to recreate GitHub's social experience.

Ghostty's departure from GitHub due to frequent outages highlights the need for a more reliable infrastructure. The issue isn't just Git, but the entire ecosystem around it, including issues, pull requests, and automation tools. While some alternatives, like SourceHut and Radicle, offer innovative approaches, they still need to mature and provide a seamless user experience.

Tangled, based on gut feel, seems promising with its focus on the social experience around code. However, it is still in alpha, and its long-term viability remains to be seen. The gap between GitHub and its alternatives lies in recreating the social layer that attracts and retains contributors. While decentralization is essential, it is not enough on its own. A new platform must also provide a shared social experience, including identities, conventions, and discovery methods, to truly replace GitHub.
