Replay says its QA tool found over 900 bugs in an experiment involving 40 apps promoted by major app-building tools, with Astra confirming and deduplicating findings. The company also describes new capabilities that reproduce user sessions from partial and redacted data.

Replay records Chromium and Node.js execution so agents can inspect program state and trace bugs to their causes. In one example, it identified a missing React click handler behind a broken download button. Replay QA launched a few months ago; the experiment concerns selected apps rather than a representative sample of web software.
