What React Developer Tools is

The extension adds Components and Profiler panels to DevTools on pages running React. When something renders wrong, it is the difference between guessing and seeing the actual props and state.

Feature coverage

  • Components panel with props and state
  • Profiler for render performance
  • Hook inspection
  • Component source navigation
  • Works on development and production builds, with reduced detail on the latter

What stands out

  • Maintained by Meta alongside React releases
  • Listing discloses no data collection
  • Essential visibility for React debugging

Tradeoffs to know

  • Store update cadence follows React releases—October 2025 at verification
  • Panels can lag on very large component trees
  • The 4.0 rating includes friction spikes after major version changes

Permissions and privacy

Page access

DevTools extensions read page context to display framework internals; it activates with DevTools rather than running persistently.

Data notes

The Chrome Web Store listing says the developer has disclosed that it will not collect or use your data.

Pricing

Free and open source. Pricing and plan limits change more often than store metadata, so use the linked developer page as the final check before subscribing.
