Your agent writes bad React, this catches it.
React Doctor deterministically scans your codebase and finds issues across state & effects, performance, architecture, security, and accessibility.
Works for all React frameworks and libraries - Next.js, Vite, TanStack, React Native, Expo, you name it.
Run this at your project root to get an audit.
npx react-doctor@latestMain.mp4
Once you have an audit, you can install the skill for your coding agent to learn from the issues and fix them in the future.
npx react-doctor@latest installWorks with Claude Code, Cursor, Codex, OpenCode, and many more.
React Doctor CI (GitHub Actions) reviews every pull request automatically and reports only the issues your change introduced, not your existing backlog.
You can configure which rules to run and how to run them in doctor.config.ts.
The CLI reports crashes, basic run traces, and anonymous usage counters to Sentry to help us fix bugs and prioritize work.
We collect:
- Environment: CLI version, platform, Node version
- Invocation: which command, package manager, and run context (whether it's local vs. CI vs. coding agent)
- Project shape: framework, React version, TypeScript, project size NO file contents)
- Rules fired: rule names and counts only (e.g.
react-doctor/no-array-index-as-key) (NO code or specific findings) - De-minified React Doctor CLI stack traces
To opt out, run: npx react-doctor@latest --no-telemetry
