About AIR

The Accessibility Internet Rally (AIR) is a unique, hands-on, intense web accessibility awareness program. Started by Knowbility in 1998 as a local one-ish-day event in Austin, Texas, the program has evolved into an international program over several weeks that brings web accessibility to nonprofits and artists, groups who want to be welcoming for all people but don’t usually have the resources for accessible web design.

During an AIR build, teams of web developers sign up as volunteers, learn the latest techniques regarding accessibility through Knowbility’s customized, intensive live trainings, and then those volunteers put their skills to work online building accessible web sites for nonprofits, non-governmental organizations (NGOs), charities, community groups, schools, artists (musicians, dance groups, painters, photographers, sculptors, poets, etc. who have public presentations of their art) and other mission-based initiatives. The main, annual competition is entirely online, involving more than 150 volunteers – making it a unique, highly-impactful and pioneering virtual volunteering event. There is also AIR-U, a version of this event for university, college and coding school students and recent graduates.

Knowbility has been advocating for websites that welcome everyone since 1998, and our nonprofit launched with the first Accessibility Internet Rally (AIR). Knowbility continues to hold this rally every year both as a way to give web designers and developers a practical outlet for using their accessible website design skills and as a way to turn nonprofits, NGOs, charities, community groups, schools and artists into supporters of accessibility and digital inclusion, reaching audiences far beyond IT professionals. We want AIR participants to play an essential, unique role in evangelizing about digital inclusion, long after the rally ends.

AIR, the first hands-on accessibility technology training program of its kind has become a formative experience in producing the next generation of accessibility leaders.”
