GitHub exports account data and bare git repositories in a .tar.gz archive. This page inspects your actual git commit histories, calculates total characters and lines of code, classifies all programming languages, finds your biggest commit, and ranks your top repositories — 100% locally in your browser.
Your GitHub data archive is streaming-decompressed inside this browser tab. Git packfiles, trees, and commit objects are analyzed locally. No repository details, access tokens, or private code are ever uploaded or transmitted to any server.
