About WebBlackbox

Web Blackbox is a Chrome extension for debugging and reproducing issues in web applications. During recording, it captures key context such as user interactions, navigation, DOM changes, console logs, runtime errors, network activity, storage changes, and screenshots, then exports everything as a replayable session archive. Users should install it because screenshots and screen recordings rarely preserve enough technical detail to explain why a bug happened. Web Blackbox keeps the full debugging context, helping developers, QA, and support teams reproduce issues faster, identify root causes, and collaborate more efficiently.
