Free and open source tool that crawls websites, checks pages against WCAG standards with axe-core, simulates keyboard navigation, and identifies accessibility
What it is
Tabwalk: the homepage
Tabwalk is a self-hosted accessibility monitoring tool that scans websites daily or weekly and identifies WCAG compliance issues. It uses axe-core for automated checks and simulates real keyboard navigation to catch keyboard traps, hidden focus states, and focus covered by sticky headers. The tool presents problems in a consolidated format, showing each issue once with affected page counts rather than listing duplicates across pages.
The platform runs entirely on your own server using Docker, with no Redis or cloud dependencies required. It integrates with CI/CD pipelines through GitHub Actions, can notify teams via Slack, Discord, or email when issues are found, and supports single sign-on through Google Workspace, Microsoft Entra ID, Keycloak or other OpenID Connect providers.
Tabwalk is released under AGPL-3.0 license with no feature limits or account requirements. The interface and rule descriptions are available in eight languages. The tool does not modify websites or claim to achieve compliance; instead, it provides a dated record of issues for teams to fix.

Quick answers
Is it really free?
Yes. The self-hosted version is AGPL-3.0 with no account and no feature limits, and it always will be.
Will it make my site compliant?
No tool can. Automated checks cover only part of WCAG. Tabwalk shows what it found and lists what a person still has to check.
What does it check?
WCAG 2.2 A and AA rules from axe-core, plus keyboard navigation that finds traps, invisible focus and focus hidden under fixed content on every page. Each problem lists matching EN 301 549, RGAA and Section 508 clauses. Best-practice rules are shown separately as recommendations.
Where does my data go?
Nowhere. Tabwalk runs on your server with its own Postgres. Pages are opened by a local browser and nothing is sent to us.
Can my team sign in with Google or Microsoft?
Yes. The dashboard has its own accounts, and single sign-on works with Google Workspace, Microsoft Entra ID, Keycloak or any other OpenID Connect provider.
