Tools
We build tools to speed up real audit work, and we point you to the community tools we trust. Everything here is meant to support a manual, expert-led audit, not to replace it.
Tools we design and maintain to make manual accessibility audits faster and more consistent.
Automated scan and in-page audit helpers, synced to your audits
Run an automated scan that pairs axe-core with CheckFox's own detection improvements to surface more real issues, map the results to WCAG, RGAA and RAWeb, use 30+ in-page helpers for manual review, and push pre-filled findings straight into your CheckFox audit.
Learn moreAudit and code skills for Claude and other AI assistants
Open-source skills that teach AI assistants to write and review code against the Luxembourg accessibility frameworks (RAWeb and RAAM), based on EN 301 549 and WCAG 2.1.
Learn moreLet your own AI agent audit, criterion by criterion
Connect an AI agent to CheckFox over the Model Context Protocol. It reads each criterion's official methodology, gathers its own evidence, and writes findings straight into your audit, one criterion at a time.
Learn moreA practical, prioritised checklist to get started
