# What is React Doctor?

React Doctor is a deterministic scanner for React security risks and performance regressions. It also catches state, effect, architecture, and accessibility issues that coding agents and lint rules miss.

Run React Doctor from a project root:

```bash
npx react-doctor@latest
```

To check every pull request, run the installer and choose **Yes** when it asks to add GitHub Actions:

```bash
npx react-doctor@latest install
```

Works with React, Next.js, Vite, TanStack, React Native, and Expo.

    },
  ]}
/>

## How it fits with linting

React Doctor complements your existing lint setup. Start with `npx react-doctor@latest`, then run the same scanner in CI or through the standalone oxlint and ESLint plugins. The CLI respects your ignore files and reads JSON ESLint or oxlint rules when present.
