    Our Contributions to the Accessibility Community

    The accessibility community was collectively struggling to agree on a common accessibility testing ruleset. We decided to make ours open source in 2015 and have since seen over 37 Million downloads as it’s made its way to becoming the standard of the industry. Coupled with a free browser extension, axe is used by over 100,000 weekly active users, helping make the web a better and more accessible place for everyone.

    Another area of importance for us is in helping drive global accessibility standards forward. Deque donates time from our top experts to contribute to WCAG standards working groups with the W3C.

    In addition to our open source work, Deque offers accessibility course scholarships for people with disabilities on Deque University.

    Our Team

    Everyone on the Deque Team shares a passion for providing equal access to the web regardless of ability.  We have helped develop international accessibility guidelines in W3C working groups, and many of our Subject Matter Experts spent years working inside large Fortune 500 companies on accessibility before joining the Deque team.
