Methodology

Honest accessibility reporting — what we catch, and what we don't.

No automated audit makes a site compliant — and any vendor who claims otherwise is the one getting sued. Here's exactly what our scan detects, what still needs a human, and why documented effort is what holds up.

What runs

Industry-standard testing — the same engine major audit firms trust.

Every scan runs on the open, industry-standard accessibility engine (opens in a new tab) used by accessibility teams worldwide, plus complementary checks — across both desktop and mobile. No black box, no proprietary tweaks to inflate your score: results you could reproduce yourself, framed for a non-developer.

Coverage

The honest number: ~35% of criteria, caught automatically.

Independent studies put automated coverage between 25% and 57% of WCAG criteria — no tool does more, whatever its marketing says. Our scan reaches roughly 35% of WCAG 2.2 AA criteria (about 30% for RGAA). The rest needs human judgment — and the guided manual audit is built in from the Scanner plan. That honesty is the point: courts reward documented effort, not overlays that promise “full compliance.”

  • WCAG 2.2 AA~35 % automated coverage
  • RGAA 4.1~30 % automated coverage
  • EN 301 549~35 % automated coverage
  • ADA Title III~35 % automated coverage
  • EAA~35 % automated coverage
  • BITV 2.0~35 % automated coverage
Known limits

What no scanner can catch — and how we cover it.

Three families of criteria stay out of reach for every automated tool on the market. Pretending otherwise is exactly what got overlay vendors fined. Our Defense plan includes a guided manual audit module to close that gap and document it.

  • Is the alt text actually useful?

    A scanner sees that an alt attribute exists. It can't tell whether "IMG_2043.jpg" describes a silver hoop earring or a product no shopper will recognize.

  • Does the focus order make sense?

    We flag missing focus indicators. We can't judge whether the tab order matches the way a real customer reads and shops your page.

  • Are language switches handled?

    A French sentence inside an English page should be tagged for screen readers. We flag a missing page language; we can't catch every mid-text switch.

Jurisdictions

Every report speaks your law — ADA, EAA, RGAA.

Pick your standard (WCAG 2.2 AA, RGAA, EAA, ADA Title III, EN 301 549…) and the scan is tied to that jurisdiction. It drives which reference applies, which criteria are checked, and how your defense PDF is framed — US ADA or EU EAA — so the document lands the way your lawyer needs it. Every scan is timestamped in UTC.

Integrity

Tamper-proof and publicly verifiable — the report your lawyer can trust.

Each report is signed and timestamped, with a public verification page anyone — your lawyer, a regulator, opposing counsel — can check by ID or fingerprint. Change a single comma and verification returns “Invalid.” This is the proof of good-faith effort that holds up when a demand letter arrives — not an overlay nobody can audit.
