We are a professional team dedicated to web accessibility and regulatory compliance. We build a11y-hd, an open source ecosystem that maps WCAG 2.1/2.2 failures to EN 301 549, the EAA and national accessibility law across 17 jurisdictions, bridging the gap between technical validation and legal compliance.

29,153 downloads on npm across all three a11y-hd packages since December 2025: engine 12,975, standards 9,611 and components 6,567. Updated 2026-10-20.

The engine

The engine scanning holmdigital.se in a terminal with a compliance score of 100/100, next to the path one finding takes from WCAG to Swedish law. The same path is described in the text below.

One command scans a page and maps every finding to the legal clauses behind it:

npx hd-a11y-scan https://example.com

In the example above, an image without alt text fails WCAG 1.1.1 Non-text Content. That is clause 9.1.1.1 in EN 301 549, which is covered by the EAA (Annex I) and the Web Accessibility Directive (Article 4). For a private company in Sweden, it falls under Lag (2023:254), enforced by PTS.
