Alameda-Contra Costa Transit District

Welcome to AC Transit's Developer Lounge

In the spirit of promoting transparency and innovation, AC Transit is proud to make our real-time API data available to developers to use in their own applications. With nearly 200,000 riders using AC Transit each weekday, we encourage you to create interesting and useful tools to make it even easier to ride public transit.

If you develop a great tool, please email us so we can let our customers know about it.
