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

UX Critic is a browser-based AI tool for reviewing website and app-screen designs. Designers, developers, founders and product teams can submit a page URL or screenshot and receive a structured critique intended to help identify usability and visual-design issues and prioritize revisions. Reviews include an overall rating and category scores, with observations linked to relevant screen areas and suggested fixes. The service offers distinct critique perspectives focused on simplicity and hierarchy, accessibility, and conversion goals, allowing teams to compare iterations using a consistent review framework. Paid plans include AI-generated before-and-after mockups for suggested changes. URL reviews support desktop and mobile viewport capture. UX Critic is intended for early design review and iterative refinement; its AI feedback is a design aid and does not replace usability testing with target users or accessibility validation.
