devtools vs Local Inspect

browser devtools brings desktop-style debugging to mobile. Invoke the extension popup on any page to capture console logs, errors, and network calls, then review everything in the host app. Run JavaScript, inspect fetch/XHR requests with headers and bodies, and monitor runtime errors and unhandled rejections. Logs are organized by tab and stored securely offline on your device. Alongside the browser extension it also has a companion app to allow easily interacting with the web app and quickly switching to see logs.
