What does Diffy do?

Diffy is a visual regression testing tool built for agencies and teams that manage complex websites. It takes screenshots of your web pages and compares them — pixel by pixel — to catch unintended visual changes before they reach users. Instead of manually checking pages after every update, you set up comparisons once and let Diffy flag broken layouts, missing content, or style drift automatically.

The tool works by letting you compare any two environments: production against staging, staging against dev, or even a live page against a Figma design. You can schedule regular monitoring runs, so unexpected changes are detected the moment they appear. Diffy goes beyond simple screenshot comparison by freezing dynamic elements (like rotating banners or live chat widgets) rather than just masking them. It can also mock content to ensure consistent baselines. For teams using local development environments like DDEV, Lando, or Docksal, Diffy provides a local container that integrates directly into your workflow. It supports CI automation, single-IP access to bypass Cloudflare, and on-premises installation.

Diffy is designed for developers, QA engineers, and project managers who need confidence before deploying changes. Agencies running multiple client sites will appreciate the time saved on code reviews. Teams using Figma can verify that the implemented frontend matches the approved designs. It's a straightforward, no-nonsense tool for anyone who wants to automate visual checks and stop relying on manual eyeballing.
