I've been building GitGauge, a way to tell if a Repo is Authentic based on fork ratio, watcher engagement and issue activity.

I'd love to hear some feedback!

The part I’m least confident about is the heuristic. Right now it uses stars, forks, watchers, and open issues. I’d be really interested in where people think that breaks down, especially for niche repos, old repos, or heavily used internal-tool style projects.
