About

Delta-QA is a visual regression testing tool for web pages, built for QA and IT teams. It automatically compares two versions of the same page and instantly flags visual differences — layout shifts, style changes, missing elements — before they reach your users. What sets it apart: a local desktop app (zero server storage, your screenshots stay with you), a no-code experience anyone can use, and a fit for small teams and Enterprise QA alike. At its core is the interactive /compare page: test visual comparison right in your browser, no signup, no sales demo. Scan, compare, validate. Delta-QA bets on simplicity and privacy over complex cloud pipelines — a direct, fast tool that secures your web deployments without sending data to third parties.

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.
