# libgit2

8 Hacker News commenters recommended libgit2 and 7 criticized it, November 2025 to November 2026. It was recommended in 6 of 13 months.

**Verdict:** Free library for working with git repositories from your own code, with broad functionality. Common caveat: not feature complete, and one benchmark found it slower than the git CLI.
