Who We Are
The Open Transit Software Foundation (OTSF) is a non-profit organization dedicated to open source transit software and technology, initially formed in order to provide governance for the OneBusAway project.
OTSF is the organizational and legal home for the OneBusAway project. OneBusAway is a suite of open source transit information tools based on real-time vehicle data.
Our members include government agencies, educational institutions, companies, non-profits, and individual contributors. A stable governance system ensures the reliability and longevity of our projects.

OTSF is a 501(c)(3) non-profit organization, and all U.S. donations are tax-deductible. We rely on support from donations and voluntary license fees for operational expenses.
