Percy vs Chromatic vs Applitools Eyes
Three visual-regression philosophies — managed rendering, Storybook-native capture and AI judgment — compared by false-positive behavior and workflow fit.

The short version
Visual regression tooling choices reduce to how each platform handles rendering determinism and human review. Percy normalizes rendering server-side across SDKs attached to functional suites, suiting E2E-centric teams. Chromatic leverages existing Storybook stories with component-level capture plus UI review workflows — natural for design-system organizations. Applitools applies vision-model classification to decide which differences matter, trading calibration trust for reduced noise on dynamic content. Budget structure matters too: per-snapshot pricing scales differently than seat/platform tiers, so model your suite size before committing.
Decision shortcuts
Storybook-heavy design system → Chromatic. Broad E2E visual coverage across frameworks → Percy. Dynamic-content-heavy enterprise matrices with budget headroom → Eyes (pilot against real history). Self-hosting mandate → evaluate Lost Pixel OSS instead of these three.
Cost modeling tip
Estimate snapshots = pages × viewports × runs/day, then check each vendor's tier math. Teams routinely underestimate viewport multiplication by 3–5×.
