I am worried about Bun

- Bun is a fast, practical JavaScript runtime that enhances TypeScript development for scripts, apps, and tooling.
- Anthropic acquired Bun in December 2025, initially reassuring users due to its reliance on Bun for Claude Code, but now concerns arise.
- Claude Code, Anthropic's AI coding tool, has deteriorated in quality, with issues like billing weirdness and restrictive policies, suggesting enshittification.
- The decline in Claude Code's user experience raises worries that Bun might suffer similar issues as it integrates further into Anthropic.
- The author is moving some projects from Bun to pnpm for package management, citing Bun's benefits but preferring pnpm for reliability.
- Despite personal shifts, the author doesn't universally recommend abandoning Bun, acknowledging its strengths and hoping for its continued excellence.
- Anthropic's model quality remains strong, but product-layer problems and lack of dogfooding in Claude Code fuel skepticism about Bun's future.
