ng-checkup

Which Angular a site runs, and whether it is in trouble: version and support, development builds, hydration, script weight.

Click the icon on any page to see which Angular or AngularJS it runs and whether it is in trouble. • Angular version and its support window: how many majors behind, out of support or not • AngularJS, alone or next to Angular, where a migration is under way • A development build running in production • zone.js or zoneless change detection • Client rendering, server rendering, and whether hydration is on or skipped for some components • How much JavaScript loads before the page is usable, and what loads later The full report tab lists every script of the site with its size. The toolbar badge shows the Angular major in the colour of the verdict. It reads only the page you click on, and only what that page already loaded. Nothing is sent anywhere: no account, no telemetry, no server. Open source (MIT). For the code itself (standalone components, signals, type safety, tests and an upgrade plan) use the ng-checkup command line tool in the repository: npx ng-checkup-cli --plan
