Sextant
Audit any repo without leaving GitHub.
Repository intelligence, right inside GitHub.
Sextant is a Chrome and Microsoft Edge extension that adds repository intelligence directly to GitHub. See SLOC, file counts, per-language complexity, repo health, CI status, searchable file navigation, PR risk signals, stale branch insights, and permission audits without leaving the page.
