Can someone please suggest any tools (free or paid version) which measure the Angular performance ? I was looking response time of API's which call via Angular to backend API. Also if tool can provide performance stats report then would be great.
For ex: Avg Load time, Rebooting time, API response time
Angular DevTools is probably the way to go for you: https://angular.io/guide/devtools#devtools-overview
You can also profile your application using flame-graphs and load time and also get insights on change detection or memory usage.
API response time can also be seen in the network tab of your browser. It is usually not important for Angular DevTools, because this is done asynchronously and does therefore not have an impact on the angular performance itself. If you want to have the whole image from enduser point of view, you can probably get some insights by using Lighthouse (https://chrome.google.com/webstore/detail/lighthouse/blipmdconlkpinefehnmjammfjpmpbjk?hl=de).
