Accessibility audits of the page the browser actually renders.

auditmysite loads each page in Chrome, reads Chrome's own accessibility tree over the DevTools Protocol and checks it against WCAG 2.2 AA. One binary, JSON for automation, PDF reports in German and English.

What it does

  1. Chrome's accessibility tree, not a static guess

    Pages are rendered in Chrome and audited through the DevTools Protocol, so JavaScript-rendered content, computed styles and the browser’s own accessible names are what gets checked.

  2. Honest WCAG coverage

    A criterion counts as automated only if a rule can report a violation. The numbers are frozen in docs/PARITY_CONTRACT.jsonc and guarded by a test; every report carries them in summary.wcag_coverage.

  3. JSON contract, PDF for people

    The JSON report is canonical English and schema-backed for automation. The PDF is tagged PDF/UA-1 and rendered in German or English (--lang de|en).

  4. Single pages and whole sites

    Audit one URL in depth, or a sitemap, a URL list or a same-domain crawl as one aggregated batch report with averages, ranking and recurring issues. Technician mode writes one JSON per page plus a flat findings.jsonl instead.

  5. Shared rules with barrierlab

    Common WCAG rules, accessible name computation and HTML conformance come from the barrierlab crates, so the same rule IDs apply in auditmysite, astro-post-audit and liveaudit.
