Diffy
What it is
Diffy provides visual regression testing for websites by capturing screenshots and highlighting changes. It detects vertical shifts and supports pixel-perfect comparison, thumbnails, individual approvals, and shareable diff links. Teams can capture pages as logged-in users, test admin pages without code, and mock dynamic content to reduce false positives in layout and style checks. AI summaries group visual changes by type and prioritize them by impact. Listed integrations include GitHub Actions, Jenkins, CircleCI, Playwright, GitHub pull requests, Zapier, Figma, Slack, webhooks, and a Claude skills plugin. Diffy also lists local integrations for DDEV, Lando, and Docksal, plus on-premises installation. The permanent free plan includes 500 screenshots per month, two environments, team management, and one month of retention. Pro costs $67 a month billed annually, with 2,000 screenshots, multiple environments, CI automation, team management, and six months of retention. CI and API access, custom environments, and history beyond one month require paid access.
