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.

About

Build better websites in less time with a stand-alone browser that makes your site more responsive, more accessible, and faster. Save hours on each project, and love every minute of it. Powerful dev tools, multiple synced viewports, full-height screenshots, over two dozen debug tools, device and media query emulation, built-in live-reloading, and more. Mobile screens to 5K monitors, get all viewports in one overview. Over 80 accessibility tests, 19 different simulators, and 20+ debug tools. Dark and light, reduced motion, screen, and print. No more manual switching! When you focus on devices you miss the hundreds of screen sizes your real users use. Check your own data. With Polypane's devices, CSS Breakpoint panes, and freeform sizing you can get the real full overview. Don't manually resize and test websites screen-by-screen. Get all your viewports in one overview, no browser resizing is needed.

Pros & Cons from Real Users

Pros

  • It gives us many of the design testing tools we need in one spot. It is also a fairly simple layout, so I can test the different options relative to the current project.

Cons

  • None really. I haven't managed to break it yet, but I keep trying.
