The short version

  • Each has a real cost: deck.gl open source framework with no commercial support tier available; support relies on community and GitHub issues; Transit coverage depends entirely on whether the local transit agency publishes a real-time feed, so quality swings sharply between well-funded metro systems and smaller regional operators.
  • They diverge on capability: deck.gl covers Core Functionality, Transit covers Real-time arrivals.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

deck.gl

  • Open source framework with no commercial support tier available; support relies on community and GitHub issues
  • Maintained by community contributors (vis.gl contributors), not by a dedicated company support team

Transit

  • Coverage depends entirely on whether the local transit agency publishes a real-time feed, so quality swings sharply between well-funded metro systems and smaller regional operators.
  • The company earns its revenue by selling agencies a paid analytics product built from rider trip data, which means the free app functions partly as a data-collection layer for a business customer, not only as a public service.
  • In-app fare payment is only available in a limited set of cities, so the headline feature is not something most riders can actually use.
  • Static schedule fallback in low-data cities is only as accurate as the agency last published, and service changes can go unreflected for weeks.
  • The app has no offline routing without a cached area, so it is not reliable for navigation in areas with poor mobile signal.
