UI Verify

UI Verify is visual testing for coding agents: visual regression and screenshot testing built so the agent that changes your UI can see what it changed. It screenshots the tests your team already has (Storybook stories, Playwright tests, or Vitest browser tests), compares each screenshot with its approved baseline, and shows exactly what changed. This connector gives Claude those visual test results directly.

With UI Verify connected, Claude can:

• Find a build by commit, pull request or branch, and see which stories changed, failed, or stayed the same
• Look at the before and after images of a change, cropped to where it moved
• Read the AI judge's call on each change (an intended change or a likely regression) with a one-line reason
• See everything a pull request did to the UI compared with its base branch, including stories it removed
• Accept or deny a change, or accept a whole build once every change is intended
• Read, write and resolve the review comments teammates left on a screenshot

Read tools never change anything. Accepting, denying and commenting are separate write tools, and Claude can only edit or delete comments it wrote, never a person's.

You need a UI Verify account with a project that uploads builds from CI (CLI or GitHub Action). Sign in once in the browser; access follows your team membership and is checked on every call. The free plan includes 10,000 snapshots a month, and open-source projects get 50,000 a month.
