Most developers open Chrome DevTools, check a couple of network requests, maybe refresh the page once or twice — and that's it.

I used to do the same.

Over time, DevTools became something else entirely for me. Not just a debugging tool, but a way to understand how the browser actually experiences

Chrome DevTools offers powerful features beyond basic debugging. The Accessibility Tree reveals what screen readers actually see, Lighthouse User Flows measure performance during real interactions, and network request blocking tests resilience. The Performance panel helps diagnose Core Web Vitals issues like LCP, INP, and CLS while teaching browser behavior. Additional features include dimming third-party code for clearer profiles, the Recorder for capturing reproducible user flows, and remote debugging on Android devices to test real-world performance constraints.
