OATS - Open Source Assistive Technology Software - is a source code repository or "forge" for assistive technology software. It was launched in 2006 with the goal to provide a one-stop “shop” for end users, clinicians and open-source developers to promote and develop open source assistive technology software. It also allows users to find other software that is free but not open source, and open-source software that is developed elsewhere, for example NVDA, Orca and FireVox.
