Contrastly

Contrastly is a CI check that fails the build when colour contrast or focus states regress.

Accessibility issues are found in audits months after they ship, when fixing them is expensive.

A CI action renders key components, measures contrast and focus visibility, and comments on the pull request with a visual diff.

Frontend teams that already run visual regression tests.

On each pull request the action renders a component matrix in light and dark mode, runs contrast and focus checks, and posts a report.

Screen reader smoke tests and a hosted dashboard of accessibility trends.
