Angular BatScanner is a Chrome extension developed by douglasduteil. This free tool is designed to help developers analyze the performance of their Angular 2 applications. With Angular BatScanner, developers can easily debug performance bottlenecks and gain insights into what is happening within their application.

One of the main features of Angular BatScanner is its ability to visualize the Angular component vocabulary. By hooking into the components' lifecycle system, developers can quickly explore a record to answer important questions such as when, where, and why a change happened, how often it's changed, and how much time a component took to react to it.

With its focus on performance analysis, Angular BatScanner proves to be a valuable tool for Angular 2 developers. It provides a comprehensive view of the application's performance and helps identify areas for improvement. The extension is available for Chrome and is categorized under Browsers > Add-ons & Tools.
