Throw Catcher – Monitor Website Activity in Real Time

Throw Catcher is a lightweight Chrome extension designed to help developers and analysts understand what’s happening behind the scenes of any webpage.

With a simple and intuitive interface, Throw Catcher tracks and displays key runtime metrics in real time:

Network Requests – Monitor how many HTTP requests the page performs
DOM Mutations – Track changes in the page structure dynamically
JavaScript Errors – Count uncaught exceptions and runtime errors

In addition, Throw Catcher allows you to export a snapshot of the collected data as a PNG image, making it easy to share insights, report issues, or document page behavior.

Why Throw Catcher?

Modern websites are dynamic and often unpredictable. Throw Catcher helps you quickly identify abnormal behavior, excessive DOM updates, or hidden JavaScript errors — all at a glance.

With built-in PNG export, you can quickly capture and share what you find with your team or clients.

Perfect for developers, QA engineers, and anyone working with modern web applications.
