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.

X Island is a free macOS menu bar app that acts as a control panel for every AI coding agent session running on your machine — Claude Code, OpenAI Codex, Gemini CLI, Cursor, and others. It surfaces permission prompts, status updates, and session questions in a compact Dynamic Island-inspired overlay so you don't have to juggle terminal windows to babysit your agents. The core problem it solves is real and immediate: when you're running three concurrent agent sessions, each waiting on a different permission approval buried in different terminal panes, you miss them and sessions stall. X Island aggregates all of that into one place. You can approve requests, answer questions, and jump directly to the relevant terminal without losing context in your editor. It's local-first, requires no account, and has zero cloud dependency. The entire value proposition is reducing friction for the growing cohort of developers who now run AI coding agents continuously throughout their workday. Built by a solo indie developer and released as free software — the kind of quality-of-life tool that the agentic IDE category hasn't yet bothered to solve natively.
Reviewer scorecard
“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.”
“I've been manually checking three terminal windows every 10 minutes to see if Claude Code is waiting on me. X Island fixes that with zero setup. This should be table stakes in every agentic IDE but nobody's built it natively yet — so this indie tool fills a real gap right now.”
“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 is a stop-gap for a problem that IDE makers will close in their next update cycle. Claude Code, Cursor, and VS Code all have roadmap items for better multi-agent coordination. Betting on a solo-built menubar app for your daily workflow feels risky when upstream tools will absorb the use case.”
“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.”
“The fact that this tool exists and has immediate traction signals how fast the 'run many agents in parallel' behavior has gone mainstream. We've crossed the threshold where developers expect to supervise fleets of AI workers — tooling will rapidly cluster around that expectation.”
“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.”
“Even for non-engineers running AI tools for content workflows, a unified notification layer for AI agent approvals is a UX pattern worth watching. The Dynamic Island aesthetic is clean and unintrusive — someone did the design work here.”
