A new server you create. It is not this listing's official endpoint. Use the publisher install when you want their URL and their credentials.
AbrirThe only Chrome extension that unifies React Timeline + Performance + Memory + Side Effects + Redux + CLS + AI analysis into a single DevTools tab — zero install in your app.
Extension version: 3.0.0 · CLI version: 2.1.2 · Author: NhoNH · License: MIT
npx @nhonh/react-debugger@latest
Then load the built extension as unpacked in chrome://extensions. Chrome Web Store listing coming soon — npx is the fastest path today.
If you debug React apps in production today, you're probably switching between four tools to chase one bug:
React Debugger unifies all of this into a single DevTools tab — zero code changes in your app, with seven analyzers and an optional AI layer for security/perf/crash insight.
The defensible triple-lock no competitor combines: CLS overlay + useEffect audit + AI analysis, all in one zero-install browser panel.
| Timeline | Performance |
|---|---|
 |  |
| Memory | Side Effects |
|---|---|
 |  |
| CLS | Redux |
|---|---|
 |  |
Bold rows = features no other tool combines into one panel.
The biggest release since launch — a full UI redesign, eight new issue detectors, an MCP server, and BYOK AI:
ChartCanvas (area / line / bars + faint grid + emphasized endpoint) powers the Memory heap-over-time timeline and the Performance render-distribution.prefers-reduced-motion, focus-visible rings, and a headless Playwright visual-regression lane.See CHANGELOG.md for the full history (including the v2.0.3 zero-lag performance work this builds on).
npx @nhonh/react-debugger
This downloads and extracts the latest extension build to your current directory. Then load it in Chrome:
chrome://extensions/You need Node 20+ and Chrome 122+.
git clone https://github.com/hoainho/react-debugger-extension.git
cd react-debugger-extension
npm ci
npm run build
Then load the dist/ folder in Chrome via the same chrome://extensions/ → Load unpacked flow.
react-debugger.zip from GitHub Releaseschrome://extensions/ → Load unpackedF12 (or Cmd+Option+I / Ctrl+Shift+I)For detailed walkthroughs of each tab, debugging strategies by skill level, and threshold reference tables, see DEBUGGING-GUIDE.md.
For 50 documented edge cases across 6 categories (Initialization, Performance Monitoring, Redux Integration, Memory & Cleanup, UI & State, CLS & Layout), see EDGE-CASES.md.
The wedge: React Debugger is the only Chrome DevTools panel that combines all seven analyzers in one tab.
npm ci # one-time install
npm run dev # rebuild on change (watch mode)
npm run build # production build → dist/
npm run test:run # one-shot Vitest run
npm run package # build + zip → react-debugger.zip
After every rebuild during dev, click the refresh icon on the extension card at chrome://extensions/ and reload the inspected page.

Active design work lives in openspec/changes/:
mcp-server-v1/ — adding a Model Context Protocol server so LLM coding agents (Claude Desktop, opencode, Cursor) can drive the extension's debugging tools programmatically. Currently in spec phase; first contributor PRs are already landing scaffolding.growth-and-contributor-attraction/ — 90-day plan to grow the project and contributor base. Week 1 (license + on-ramp) shipped May 2026.Every star helps more React developers discover the project — and it's the single most useful signal you can send the maintainer that the work matters. One click. Big difference.
You can also 👀 Watch releases to get notified when new tabs (or the MCP server) ship.
