Hi Product Hunt 👋 I built **React Debugger** because I kept wasting hours hunting down React performance issues, memory leaks, and subtle effect bugs. React DevTools is great—but I wanted a *single panel* that shows **performance + memory + anti‑patterns** together, without adding extra code. React Debugger helps you: - Profile render counts, duration, and triggers - Track memory growth to catch leaks early - Detect anti‑patterns (mutation, missing deps, stale closures) - Inspect Side Effects + CLS - Debug Redux with time‑travel and live state edits Install: `npx @nhonh/react-debugger` Repo: https://github.com/hoainho/react... I’d love your feedback on what to improve next 🙌
