Angular Scan

Visualize Angular component re-renders and spot wasted change detection on any dev-mode page.

Angular Scan shows you which components re-render, and which renders were wasted — no changes to your app required.

Enable it on any Angular dev-mode page and you get:
• Flash overlay — yellow when a component renders, red when the render was unnecessary
• Live render-count badges on each component
• A sortable table of renders, wasted renders, and render rate
• One-click copy of a component's source path
• Exportable JSON/CSV reports and a full-page report viewer

Dev-mode only. Works with both zone.js and zoneless Angular apps.
