Are you interested in hacking on OneBusAway to add a new feature or fix an annoying bug?  Maybe you want to write a new mobile app powered by our Open Transit Data?  We want to help you get involved.

Open-Source

OneBusAway is open-source software, which means we release all the code that powers OneBusAway.  For instructions on accessing the source and getting involved with development, check out our GitHub page:

API Service

The same RESTful API service that we use to power our OneBusAway mobile apps is available to you for writing your own applications.  For instructions and documentation about accessing the API, check out:
