In their own words
AccessLint
AccessLint checks accessibility during development, on pull requests, and on live sites. Its WCAG 2.2 engine has 95 rules and a stated 53ms median audit across 5,000 real-world sites. Pull-request reviews inspect changed files and leave inline comments with the relevant rule and a suggested correction, but do not fail builds or block merges. Deploy-triggered scans require Starter or Pro, run asynchronously, and also do not synchronously fail builds. Saved user journeys can run daily, with email alerts for new violations or changes against a baseline. The toolkit provides checks for Playwright, Vitest, and Storybook, while pull-request reviews use a GitHub App. Starter and Pro include shareable read-only evidence reports with before-and-after screenshots of affected elements. Free covers public-repository pull-request reviews, one daily monitored flow, and violation trends. Starter costs $19 a month or $190 a year; Pro costs $349 a month or $3,490 a year. AccessLint says automated checks alone cannot make a site compliant.
