Automated accessibility testing for every pull request

AccessLint CI reviews your pull requests for accessibility issues and comments inline — so you can fix problems before they ship.

AccessLint bot reviewing a pull request on GitHub, showing inline comments for accessibility issues like missing alt attributes and links without discernible text.

How it works

2. Open a PR

AccessLint automatically audits the changed files in every pull request for WCAG violations.

3. Fix before merge

Review inline comments with clear explanations and fix accessibility issues before they reach production.
