UI Verify Review 2026

Visual regression testing for Playwright, Storybook and Vitest that uses an AI judge to classify UI changes and exposes results to coding agents over MCP.

UI Verify is a visual regression testing service built for teams that use Playwright, Storybook or Vitest browser mode, and positioned around workflows involving AI coding agents. When a pull request is opened, it captures screenshots of the components and pages the change touches, compares them with stored baselines, and posts a check and comment on the GitHub PR.

Its central feature is an AI judge that labels each visual difference as an intended update, a real regression or a flake, and records its reasoning. The judge does not merge anything; reviewers make the final decision, can comment on specific pixels in threads, and accept or deny each change. Capture is designed to reduce noise by pinning animations, timers, fonts and async data, and only affected screens are re-rendered while unchanged ones carry forward. Every accepted baseline is versioned. Chromium is available on all projects, and Storybook projects can add Firefox and Safari (WebKit) at desktop and phone widths. Teams can also upload PNGs from other tools, including native and React Native apps.
