React Render Tracker is a devtool library that visualizes a React app's component tree state over time to uncover performance issues from unintended re-renders and unmounts. It complements React DevTools with an event log, props/context update matrices, and rendering timings per fiber.
Use cases
- find why a React component re-renders too often
- track component mounts and unmounts over time
- investigate which component causes another's update
- debug useMemo and useCallback recomputations
- analyze context usage and provider consumers
- profile React rendering performance in development
When to choose
- you need to diagnose unintentional re-renders in a React 16.9+ app
- React DevTools isn't enough to trace update causes
- you want a component tree timeline including unmounted components
When to avoid
- you need full component state inspection rather than state diffs
- you're profiling production builds, where some data isn't captured
- your app doesn't use React
