# Monitor Visual Changes

Websites change constantly -- deployments introduce UI updates, third-party scripts modify layouts, CMS edits alter content, and A/B tests rotate variations. Without visual monitoring, these changes go unnoticed until a user reports a broken layout or a stakeholder notices something looks wrong in a meeting.

Capturing screenshots on a regular cadence creates a visual history of your website. By comparing screenshots from different points in time, you can detect unintended changes, verify that deployments rendered correctly, and maintain a visual audit trail. This is especially important for large sites where changes in one section can have cascading visual effects.

This approach complements automated testing by catching the class of bugs that functional tests miss -- CSS regressions, layout shifts, font changes, color inconsistencies, and broken responsive designs. A page can pass all functional tests while looking completely wrong visually. Screenshot monitoring catches those failures.
