"WebBlackbox records what happened inside your web app, packages it into a portable .webblackbox archive, and lets you replay the session later with timeline, screenshots, network, console, storage, DOM, and performance context intact."
"Record user interactions, navigation, console output, runtime errors, network traffic, storage activity, screenshots, and performance signals in one archive. Choose between lite capture for lower page-thread overhead and full capture for CDP-backed debugging detail."
"Replay sessions with a rich Player UI and generate curl, fetch, HAR, Playwright, and bug-report artifacts. Connect archives to AI workflows through the MCP server."
WebBlackbox is a flight recorder and time-travel debugger for web applications. It captures user interactions, navigation, console output, runtime errors, network traffic, storage activity, and performance signals. The recorded data is packaged into a .webblackbox archive for offline replay. Users can choose between lite and full capture modes, export archives for team collaboration, and connect to AI workflows. The hosted Player allows inspection of timelines, screenshots, and generated artifacts, enhancing debugging efficiency.
