The Zig programming language project has announced its migration from GitHub to Codeberg, citing a range of concerns with GitHub’s service. The shift was spurred by what Zig’s lead developer, Andrew Kelley, described as a decline in performance due to the bloat of JavaScript frameworks, unreliable GitHub Actions, and intrusive AI features that conflict with Zig’s policy against LLM (Large Language Model) usage.
The Zig Software Foundation highlighted several issues with GitHub, including the neglect of critical bugs. Notably, a CPU-spinning bug in GitHub’s <code>safe_sleep</code> script went unresolved for years, leading to CI runners hanging indefinitely. Zig’s leadership has been critical of Microsoft’s focus on AI, which they argue diverts attention from essential platform maintenance.
Financially, the transition comes with significant risks. GitHub Sponsors contributed over $170,000 to the project in 2024. The Zig team has requested sponsors to transition their support to <a href="http://Every.org" target="_blank" rel="noopener nofollow">Every.org</a>, reflecting concerns about GitHub’s future as a sustainable platform for open-source projects.
The migration has received a mixed reception within the developer community. Some express concerns over the difficulties that may arise from leaving GitHub, the dominant hosting platform. However, Codeberg, a non-profit Git hosting service, has seen a significant increase in membership since January 2025, partly due to broader dissatisfaction with GitHub.
As of now, Zig’s GitHub repository has been made read-only, and all new issues are to be initiated on Codeberg, starting at number 30000. While existing issues and pull requests on GitHub will remain open, they will not be migrated to the new platform.
This move by the Zig project underscores a growing conversation among developers about the alignment and priorities of major tech platforms, and it raises questions about whether other projects will follow suit.

The Zig programming language project has migrated from GitHub to Codeberg, a non-profit Git hosting service. Lead developer Andrew Kelley cited declining GitHub performance, unreliable Actions, unresolved critical bugs, and intrusive AI features as primary reasons. The move risks over $170,000 in annual GitHub Sponsors funding, which the team is transitioning to Every.org. The GitHub repository is now read-only with new issues starting on Codeberg at number 30000. This migration reflects growing developer concerns about major tech platforms' priorities and could influence other open-source projects.
