git log | wc -l gives you one number. cloc doesn't know about history. GitHub's "Insights" tab is behind a login, and it lies by omission (no bus-factor, no streaks, no hotspots). gitstats runs locally in your terminal, reads only what git already tells it, and surfaces the metrics that actually help you ship.

Counts how many commits touched each file. Files at the top of the list are where churn concentrates — where bugs cluster, where refactors avoid, where onboarding hits hardest. A classic signal from Your Code as a Crime Scene, computed in under a second on any repo.
How many authors do you need to read to understand 50% of the repo's history? If the answer is 1, you have a people-risk problem, not a code problem. gitstats surfaces the raw number plus a ⚠ warning when it's ≤ 1.
Longest and current consecutive-day commit streak. Useful for solo-dev retros, not as a productivity cudgel.
Reads refs/tags, computes average gap between tags, and shows your last 5 release intervals. Useful for "are we shipping faster or slower than last quarter?" without pulling up GitHub.
Additions vs deletions per month as stacked green/red bars. Fast visual signal for "is this codebase growing unbounded or being maintained?"
--range v1.0..v2.0 --hotspots tells you which files changed most between two releases. Great for changelog prep and regression risk review.
Every git invocation uses spawnSync('git', [...args]) — no shell interpolation — so --author "x\"; rm -rf /" is just a query with no matches, not a catastrophe.
