Lastest is an open-source verification of development, visual regression and E2E testing platform for web apps. An AI agent records your tests by watching you click through the app, generates deterministic Playwright code, and CI replays the runs at zero token cost. Three diff engines (pixel, structural, perceptual) keep noise low. Self-host via Docker — unlimited screenshots, no per-snapshot fees, no UI ever leaves your network. Best alternative to Percy, Chromatic, Applitools, BackstopJS.
