Prevent UI bugs from reaching production through automated screenshot comparison that integrates directly with GitHub workflows. Compose visual tests using existing Storybook, Next.js, and Playwright setups, mask irrelevant elements during comparisons, execute custom browser code before captures, configure thresholds for change detection, test across multiple browsers and breakpoints, run tests in parallel for speed, approve or reject changes through streamlined review flow, and combat flakiness with automatic retries and custom wait utilities.
