Query and inspect components via the React Fiber tree — no DOM needed. Use testID, text, or hierarchy selectors.

Inspect React state hooks (useState, Zustand, etc.) of any component. Track state changes in real time.

Track component mounts, re-renders, and unnecessary renders. Find performance bottlenecks without React DevTools.

Intercept XHR/fetch requests and inject mock responses. Test edge cases without a backend.

Tap, swipe, screenshot, assert, eval, and more — 42 tools across 12 categories, all callable by AI.

Write scenarios in YAML — tap, assert, wait — and run them locally or in CI without AI.

Pure JavaScript runtime + host CLI tools (adb/idb). No native module to install, no linking, works with any RN project.

Cursor, Claude Desktop, Claude Code, GitHub Copilot, Windsurf, Antigravity — works with any MCP-compatible client.
