Lastest vs Lost Pixel: Open-Source Visual Testing Compared

Lastest vs Lost Pixel: Open-Source Visual Testing Compared

Lost Pixel and Lastest are both free, open-source visual regression testing tools with very different approaches.

Two-column comparison: Lost Pixel (Storybook + static snapshots, paid CLI-only dashboard, 1 diff engine) versus Lastest (any URL and flow with AI generation, free self-hosted dashboard, 3 diff engines plus OCR), both free and open source
Both tools are free and open source; the real split is scope and what ships in the OSS build.

Lost Pixel focuses on Storybook and static pages. Lastest focuses on full application testing with AI generation and a complete review dashboard.

Scope

Lost Pixel: Storybook stories and static page snapshots. No user flow testing, no interactions.

Lastest: Full application testing - any URL, any flow. AI-generated tests, no-code recording, spec-driven generation.

Flow diagram: Lost Pixel takes a single input (Storybook stories) into one component snapshot diff, while Lastest funnels many inputs (URLs, OpenAPI specs, PRDs plus recording) into AI test generation that produces full-app and flow coverage reviewed in a dashboard
Lost Pixel maps one input to one snapshot diff; Lastest funnels many inputs through AI generation into full-app coverage.

Dashboard

Lost Pixel: OSS is CLI-only. Dashboard requires paid Lost Pixel Platform.

Lastest: Full web dashboard (self-hosted, free) with team management, AI analysis, approval workflows, accessibility auditing.

When Lastest Is Better

  • Full-page and user flow testing
  • AI test generation
  • Dashboard with team collaboration
  • Three diff engines with OCR handling
  • Testing templates for different app types
