Data in Transitland systems are covered by a variety of terms and licenses. See Transitland data and API terms and attributions.


Transitland is powered by open-source software. The transitland-lib library is at the core of Transitland version 2 and is released under a "dual license" model:

  • open-source for use by all under the GPLv3 license
  • also available under a flexible commercial license from Interline

The web app that powers this website and many other other components are also publicly available on GitHub.

Interline keeps private server configuration, database configuration, and back-end workflows that are particular to the deployments. Contact Interline for consulting services if you need support customizing a deployment of Transitland tooling.
