Help keep creative tools free.
AOS resources are made possible through grants, sponsors, and people who believe creators deserve access to professional tools and knowledge. Free access still requires paid work: artist fees, development, hosting, documentation, and music production.
Your support helps fund development, testing, documentation, music production, education, and distribution.
