Build Status


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 (Heritrix crawler 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
