Description
Hover over any element on a React app to see which component rendered it. WhoRenderedThis is a developer tool for understanding React UIs by showing you which React component rendered any element on the page. Activate it with one click, then hover over the UI to see the nearest component name and an on-page highlight. Pin a selection to inspect it more carefully, view its parent component chain, and copy the component info to your clipboard. Why install it: - Faster debugging: jump from “what I see” to “what rendered it” - Works on most React sites with zero setup - Lightweight and privacy-first: no analytics, no data collection, no network requests Notes: - Source file + line numbers are shown when available (best in dev builds). - The extension only runs when you click the extension icon.
