Diffy is a visual regression testing platform designed to help development teams and agencies detect visual changes before and after website releases through screenshot comparison. The page clearly positions it for agencies that βmanage complex websites,β with typical use cases including legacy site maintenance, style fixes, responsive testing, and pre-launch regression review.
Diffy covers screenshot capture, difference detection, review collaboration, and automation integration. It supports approving changes one by one, marking bugs, quickly reviewing from thumbnails, filtering diffs, and using before/after sliders plus pixel-level comparison. Its comparison algorithm can detect vertical shifts, reducing large false positives caused by an entire page moving downward.
For dynamic websites, it offers capabilities such as mocking dynamic content, removing or masking elements, delaying screenshots, scrolling pages, injecting CSS/JavaScript, setting headers/cookies, and capturing screenshots in logged-in states. It also supports screenshots of local development sites, making it suitable for validating styles and layouts before deployment.
The main content does not restrict Diffy to any specific language or framework. It can be integrated into CI/CD workflows such as GitHub Actions, Jenkins, and CircleCI via CLI, and it also supports uploading screenshots generated by Playwright or other functional testing frameworks for comparison.
Its ecosystem integrations include Slack, Email, Webhook, Zapier, Figma, as well as examples for Pantheon and Tugboat. For team collaboration, it provides admin, developer, and read-only roles, shared diff links, notification thresholds, bulk operations, and YAML configuration import/export.
Pricing is based on screenshot volume. The free plan includes 500 screenshots per month, 2 environments, team management, and 1 month of data retention. The Pro plan starts at $67/month when billed annually, with multiple environments, CI automation, and 6 months of data retention.
The page does not disclose payment methods, enterprise plans, self-hosting, or open-source information, so these points need further confirmation.
Its strengths are a complete visual testing workflow, with particular attention to complex pages, dynamic content, and human review processes. Its integrations also make it suitable for engineering-oriented teams.
The downsides are that the documentation is only linked but not detailed on the page, the Pro pricing tiers are incomplete, and there is no information about open-source or self-hosted options. Diffy is a good fit for agencies maintaining Drupal, WordPress, or other complex websites, web development teams, and teams that need to automatically detect visual regressions in pull requests.
The main content does not provide information about access from mainland China, node availability, payment options, or compliance. For now, this can only be marked as unknown. If access is unstable, alternatives such as Percy, Chromatic, or Applitools can be evaluated, or teams can build their own screenshot regression workflow based on Playwright/BackstopJS.
