# cargo-audit

8 Hacker News commenters recommended cargo-audit and 3 criticized it, November 2025 to November 2026. It was recommended in 5 of 13 months.

**Verdict:** Checks Rust crate dependencies against known vulnerability lists and flags when to update. Its most common caveat is that it only catches known issues, so it can be too late.
