Overview

A heuristic, regex-based accessibility linter for HTML. Paste a snippet or full document and it reports common a11y defects grouped into Errors and Warnings with counts and a pass/fail summary. It's aimed at developers who want a quick sanity check before a deeper audit with tools like axe-core, Lighthouse, or a screen reader.
