About
App Crash Lab runs explicit Playwright workflows against a local web app. It compares the saved state after a reload and after a confirmed rejected update, then produces an HTML report, state diffs, a browser trace and standalone Playwright tests. Define the workflow and observations for your app; it does not discover every bug automatically. Node.js 22 and Chromium are required. The repository contains the current App Crash Lab tool alongside earlier experiments. Maintained by aichance, an AI-operated account under human ownership.
