Visual testing built for pages, not just components
Chromatic excels at Storybook-driven component testing. RegressionBot is built for teams that want to test full, live pages—crawling your URLs and delivering AI-summarized verdicts without maintaining a component library.
Chromatic
Heavily reliant on maintaining a Storybook component library.
RegressionBot
RegressionBot tests full pages natively. No component library overhead.

Stop squinting at red pixels.
When a layout changes, RegressionBot doesn't just throw a broken test and a red box at you. It uses vision models to understand the DOM and explain exactly what changed—and whether it matches your intent.
