RegressionBot vs Chromatic

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.
