Lastest is the open-source verification of development, alternative to Percy, Chromatic, and Applitools. It is a complete visual regression and E2E testing platform: AI test generation, deterministic Playwright replays, three diff engines (pixel, structural, perceptual), a review dashboard with baseline approval, and a multi-tenant runner that works out-of-the-box with GitHub Actions, GitLab CI, and Jenkins.

Why teams pick Lastest: Per-screenshot pricing (Percy, Applitools, Chromatic) makes visual testing expensive at scale. Self-hosted DIY tools (BackstopJS, Lost Pixel) lack AI test generation and a review UI. Lastest is the only tool that pairs Applitools-class perceptual diffing with full self-hosting, AI test recording, and a dashboard — at $0/month.

Who it's for: Solo founders shipping daily, developers stuck owning QA without a QA team, SaaS startups on tight runways, and enterprises with data-residency requirements (HIPAA, GDPR, SOC 2). Source code is FSL-1.1-ALv2 on GitHub; one docker compose up and you're running.
