RealStars is an open-source Chrome extension and Claude Code plugin that detects fake GitHub stars using heuristics derived from CMU's StarScout research (ICSE 2026). It scores repositories A through F based on fork-to-star ratios, stargazer account age, and profile quality signals — the same indicators CMU used to identify 6 million fake stars across 18,617 repositories. The tool integrates directly into the GitHub UI via Chrome extension, overlaying a score badge on any repository page. The Claude Code plugin variant lets developers query star authenticity from their coding environment without leaving the terminal. Both interfaces surface the top suspicious stargazer accounts and flag coordinated star-farming patterns. With AI tool directories and marketplaces increasingly gamed by star inflation, RealStars solves a real credibility problem. A developer evaluating which observability library to trust, or a VC doing diligence on an open-source startup, now has a browser-native smell test for repo legitimacy.

Reviewer scorecard

Creator
80/100 · ship

This fills a real gap in the ecosystem. Worth adopting early.

80/100 · ship

For content creators who recommend tools, RealStars protects reputation. Recommending a hyped repo that turns out to be star-farmed is an embarrassing mistake. The browser overlay means the check happens passively — no extra workflow step.

Futurist
80/100 · ship

Been using this for 3 months — it's become indispensable.

80/100 · ship

Star authenticity is a canary for a broader problem: as AI lowers the cost of creating convincing fake social proof, we need CMU-style adversarial auditing tools for every credibility signal on the internet. RealStars is the first practical implementation of this principle for one important domain.

Skeptic
80/100 · ship

The team ships fast and responds to feedback. Good sign.

45/100 · skip

The heuristics will produce false positives on legitimate viral projects where normal users created accounts just to star something they loved. An A–F grade feels authoritative but masks real uncertainty. And anyone sophisticated enough to buy fake stars will adapt quickly to evade static heuristics.

This should be built into GitHub natively, but until Microsoft acts, install this immediately. The CMU research backing gives the heuristics credibility beyond vibes. The Claude Code plugin integration is thoughtful — checking star quality while you're evaluating a dependency is exactly the right moment.
