Sometimes you want to look at a repo without clicking through five GitHub pages. Shape-of-the-project stuff. What's the default branch, which languages, who's actually contributing, how old is the last release, is it MIT or proprietary.
The GitHub Repo Visualizer is that single page. Paste any public GitHub URL; it renders the stars-forks-issues-watchers box, a language composition bar chart, the top 10 contributors by commit count, and the most recent releases. All from GitHub's public REST API, no auth required (subject to the standard 60 requests/hour IP rate limit).
Pair it with the GitHub Authority Score. The visualizer shows you what a repo looks like; the authority score tells you whether it's pulling its weight as an entity signal for the brand behind it.
