About
Diffy is a cloud-based visual regression testing platform for websites. It screenshots every page you list, at every breakpoint you choose, on production, staging, development or pull request environments, and compares them to show exactly what changed.
- Compare two environments (e.g. staging vs production) or the same site before and after an update, on demand or on a schedule
- Mask, remove or mock dynamic content; custom CSS and JS; log in before capture (Drupal, WordPress and Netlify presets)
- Review UI: approve from thumbnails, group the same change across pages, shareable links
- AI Summary of each comparison, sent to Slack, email, webhooks and GitHub/GitLab PR comments
- Integrations: GitHub, GitLab, CircleCI, Pantheon, Upsun, CLI and API, Claude Code plugin
Built for agencies and teams maintaining Drupal and WordPress sites. Free plan: 500 screenshots/month.

About
Percy is an all-in-one visual testing and review platform that automates visual quality assurance by capturing screenshots of your web, mobile, or component UI, comparing each snapshot against a baseline, and highlighting any unintended visual changes to ensure pixel-perfect consistency. The platform supports integration with popular test frameworks, CI/CD pipelines, and component libraries, enabling teams to capture snapshots at each commit, review diff overlays, approve changes, suppress noise from dynamic elements, and maintain stable visual approval workflows. Percy works across multiple resolutions, browsers, devices, and viewports, and offers features like cross-browser testing, full-page capture, branch-aware baseline selection, intelligent diff filtering, and built-in collaboration tools (approve, request changes, comment). With support for SDKs in major languages and frameworks (e.g., Playwright, Cypress, Storybook), teams can embed Percy into their existing test suites.
