Lost Pixel is an open-source visual regression testing tool and GitHub Action that compares screenshots from Storybook, Ladle, Histoire, page screenshots, or custom Playwright/Cypress flows against baselines. It ships as an OSS engine plus a managed SaaS platform, positioned as an alternative to Percy, Chromatic, and Applitools.

Use cases

  • catch visual regressions in UI components before shipping
  • run visual regression tests on Storybook stories in CI
  • compare full page screenshots on pull requests
  • test UI across multiple browsers and device breakpoints
  • set up an open-source alternative to Percy or Chromatic
  • mask or hide dynamic elements before screenshot comparison

When to choose

  • you want visual regression testing tightly integrated with GitHub Actions
  • you already use Storybook, Ladle, Histoire, or Playwright and want screenshot checks
  • you need an affordable or self-hostable alternative to Percy/Chromatic/Applitools
  • you need per-screenshot thresholds, masking, and multi-browser/breakpoint runs

When to avoid

  • you need a long-term supported product - the team is joining Figma and sunsetting the product
  • you need non-web visual testing (native mobile or desktop apps)
  • you require a managed platform with guaranteed future support and SLAs
