Bun support is now limited and deprecated | Hacker News

Bun has been marked limited and deprecated, triggering backlash in a Hacker News thread.

Commenters criticized the project’s rewrite, including the move from Zig to Rust and an incomplete feature set.

Some also raised concerns that agentic AI or “vibe coding” may have shaped development practices.

The announcement has weakened trust in Bun as a stable production runtime for teams that value maintainability and predictability.
