Goodbye GitHub: Zig developer ditches “sinking ship” over Microsoft's AI

GitHub Actions has reached the point where CI scheduling feels nondeterministic. In Zig's case it stalled the entire build pipeline so badly that even manual retries weren't enough to recover. Andrew Kelley attributes this to Microsoft's AI-first shift and the explicit "embrace AI or get out" stance from leadership, which he argues has degraded engineering priorities. Zig's move to Codeberg is a concrete response to platform reliability falling below an acceptable threshold, even with years of ecosystem lock-in.

Concurrent with the Bun acquisition announcement, Zig Software Foundation migrated from GitHub citing Microsoft's AI focus and violations of their strict no-LLM contributor policy. Andrew Kelley abandoned 10 years of GitHub infrastructure rather than tolerate AI feature encroachment, demonstrating the rigidity of Zig's anti-LLM governance stance.
