A11y Lint is a lightweight developer-focused linter that scans HTML, CSS, and JSX files for common accessibility issues during development — right in your code editor.
👷🏽 Why We Built This
Web accessibility is too often an afterthought, discovered only in audits or by users who face barriers. Popular tools like Axe are excellent, but they:
Rely on runtime in-browser testing
Are not always friendly for dev-first feedback
Can feel too heavy or complex for small projects
A11y Lint solves this by working like ESLint — it gives instant feedback in the editor as you type.
