Maintainers

Bun does not publish a formal CODEOWNERS file. The list below is derived from git log --since="365 days ago" over the relevant subdirectories — it tells you who has been touching each subsystem most recently, which is usually who you want to ask first.

This is not authoritative. Bun has 906 unique committers historically; the names below are statistical hot spots, not gatekeepers.

How to find owners for a path

# Most-frequent author touching a directory in the last year
git log --since="365 days ago" --pretty='%an' -- src/install/ | sort | uniq -c | sort -rn | head -5

For systems-level questions, the CLAUDE.md files near the code (src/CLAUDE.md, src/js/CLAUDE.md, test/CLAUDE.md) often reveal authoritative conventions.
