As React applications scale, it becomes more difficult to track state and to have a holistic overview of the component hierarchy. Realize is a tool to help developers visualize the structure and state flow of their React applications, especially when they are growing in scale and complexity. It currently supports React v.16.8.


  1. You must have React Dev Tools installed to use Realize for React. Install it from here.
  2. Realize is best used on non-deployed applications. This uglification of deployed websites makes the component structure pretty unreadable.

💻How to use

  1. Click the blue 'Add to Firefox' button
  2. Once installed, navigate to your React website
  3. Open the dev tools window and click on the Realize panel
  4. Trigger a state change to populate the component tree
  5. Like us on Github

🔥Functionality: Zoom & Pan - Hold down shift to enable dragging and zooming on the tree (to recenter just click the center button)
