Tanaguru is an opensource (AGPL license) website assessment tool. It is dedicated to accessibility (a11y) audits, and focuses on reliability and high level of automation.


Four kinds of audit:

  • page audit
  • entire website audit (crawler4j embedded)
  • scenario audit
  • offline file audit

(That's the DOM that is tested, thus dealing with JS/AJAX/ARIA)


  1. Automate as much as we can and even more :)
  2. Be 200% reliable (don't give erroneous result)
  3. have technological fun
