SnapDiff

Capture pages, compare A/B screenshots, annotate, and save locally.

Capture web pages, compare screenshots, annotate changes, and keep your work local. SnapDiff helps you review page changes without a SnapDiff account or CI setup. Capture a viewport, full page, or selected area. Compare A/B screenshots side by side or inspect pixel differences, then annotate findings and export your evidence. FREE FEATURES • Unlimited capture and review workflows • Single, A/B, and Multi capture, with 2–5 images in a Multi group • Responsive viewport presets and browser-language simulation in Chrome • Arrows, shapes, pen marks, and text annotations • Full-quality PNG, JPEG, WebP, and A4 PDF exports • SnapDiff branding and capture timestamps on exports PRO FEATURES Pro adds optional local axe accessibility checks, clean or custom watermarks, and controls for capture timestamps. Pro costs USD $9.99 for one year, paid once with no automatic renewal, and supports up to three browser installations. Taxes may apply. PRIVACY Screenshots, page URLs, annotations, and accessibility reports stay in your browser profile. SnapDiff does not upload captures or reports. License activation and validation send licensing information to Dodo Payments separately. IMPORTANT LIMITATIONS SnapDiff is for desktop Chrome 120+. Responsive presets change CSS viewport dimensions; they do not simulate physical devices or other browser engines. Language simulation requires the site to support the selected language and reloads the tab. Accessibility scans cover the loaded main document and open shadow roots, not embedded frames or closed shadow roots. Findings are not an accessibility certification. A/B means screenshot comparison, not a statistical experiment.
