Accessibility Checker

Automated WCAG, Section 508 & EN 301 549 compliance.

Scan your websites and PDF documents for accessibility problems, track them over time, and produce the conformance reports auditors and buyers ask for. One scan reports against every framework view — WCAG 2.2 AA, U.S. Section 508, and EU EN 301 549 — so you find issues once and report against all three, and PDF/UA (ISO 14289) checking covers your documents too.

Everything you need, nothing you don't

Automated Scans
Render each page in a real browser and run a comprehensive rules engine to catch color-contrast, missing labels, ARIA, keyboard, and structure issues — with the exact elements and WCAG success criteria that failed.
One Scan, Every Framework
A single scan reports against WCAG 2.0/2.1/2.2 (A & AA), U.S. Section 508, and EU EN 301 549 — no re-running for each standard. Score, issue counts, and per-criterion status update together.
Trend & Regression Tracking
See a site's accessibility score move over time. When a new scan introduces more critical or serious issues than the last, admins are alerted automatically so regressions never ship silently.
Manual Audit Checklists
Automated testing catches ~40% of issues; the rest need a human. Work through a reviewer checklist of the criteria that can't be automated, record pass/fail with notes, and sign off — auto-failures from the scan are pre-filled.
VPAT / ACR & Statements
Generate an ITI-style VPAT / Accessibility Conformance Report (Supports / Partially Supports / Does Not Support) and publish a hosted, accessible Accessibility Statement page for your site — the documents procurement teams require.
Scheduled & Authenticated
Schedule recurring crawls so compliance stays current, and scan pages behind a login by supplying a username/password and login URL (MFA-free service accounts). Scans run on a dedicated worker — never on your app tier.
API, MCP & Orchestration
Queue scans and pull results via the REST API and MCP tools, and fire Orchestration workflows or webhooks on every completed scan or detected regression — route a new issue straight into your Issues app.
PDF/UA document checking
Accessibility isn't only web pages. Upload PDFs and check them against PDF/UA (ISO 14289) — tagging, reading order, language, title, and image alt text — with a machine report plus a manual-review checklist for the human-only checkpoints.
CLI & Browser Extension
Test where you build. A stdlib-only command-line tool queues a scan and fails your CI build when critical or serious issues exceed your thresholds — no Chromium to install. A Chrome/Edge extension scans any open page in one click, including pages behind your own login, and can queue a full hosted scan into your project. Both connect with a scoped API token.

Accessibility Checker is just one of many apps — all included.
