How to Monitor Visual Changes with Claude

Monitor website visual changes with Claude and ToolRouter. Detect unintended UI regressions.

Claude makes visual change monitoring a conversational process in your terminal. Capture a baseline, deploy changes, then ask Claude to capture and compare. Claude identifies visual differences and discusses their significance, answering follow-up questions like "is that layout shift intentional?" or "does the mobile version have the same issue?" in a natural dialogue.
