Lastest

AI-recorded visual regression tests you can actually trust.

Lastest is the free, open-source, self-hosted alternative to Percy, Chromatic, and Applitools. An AI agent records you clicking through your running web app and generates Playwright tests with multi-selector fallback. Replays are deterministic and token-free — your CI bill never scales with your test suite. Three diff engines side-by-side (pixelmatch, SSIM, Butteraugli) keep noise low. Self-host via Docker for unlimited screenshots and full data residency, or use Lastest Cloud for managed CI runners. License: FSL-1.1-ALv2.
