Project overview
The short version
App Crash Lab starts with one working save flow and checks what happens to its saved values after a reload or an invalid update. Developers describe the local app, actions and expected values in a JSON contract. The tool produces comparisons, traces and a standalone Playwright test that can be kept for later runs. Its public examples make the main limitation concrete: a test can pass while missing a value it never checked. The project is MIT-licensed, requires Node 22 or newer for the CLI, and says the runner makes no model calls.
