The short version

  • Each has a real cost: Potree there is no vendor, no support contract and no service level, so anything you build on Potree is your organisation’s responsibility to maintain when a browser update breaks rendering.; 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: Potree covers Octree streaming, 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.

Potree

  • There is no vendor, no support contract and no service level, so anything you build on Potree is your organisation’s responsibility to maintain when a browser update breaks rendering.
  • Conversion is a separate manual step with PotreeConverter, and building an automated publishing pipeline around it is engineering work the project does not provide.
  • Rendering quality and performance depend on the client machine and WebGL support, so a client on a locked-down corporate laptop with poor graphics may see a viewer that stutters or fails outright.
  • A WebGPU rewrite, Potree-Next, is in progress and is not a drop-in upgrade, so current integrations face an eventual migration with no vendor to manage it.
  • There is no access control, user management or audit layer; anyone with the URL sees the data unless you build authentication around the static files yourself, which is a real problem for confidential sites.

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.

Answered from the vendors’ own pages

Potree: Does Potree cost anything?

No. It is open source and free. You supply the hosting, which for a static viewer is inexpensive.

Transit: Does Transit cost anything to use?

No. The rider app is free with no subscription and no ads; the company earns money separately by selling agencies a paid data and communication platform.

Potree: Is there commercial support?

No. There is no vendor and no support contract. Support is GitHub issues and the community.

Transit: Does it work in every city?

No. Coverage depends on whether the local transit agency publishes a GTFS or GTFS-realtime feed; some smaller markets have static schedules only.

Potree: Who maintains it?

It originated at TU Wien and is maintained principally by Markus Schütz, with community contributions.

Transit: Can I buy a bus or train ticket in the app?

Only in cities where the local agency has integrated fare payment; elsewhere you still need the agency app or a physical ticket.

Potree: Can it handle very large clouds?

Yes, hundreds of millions of points, because PotreeConverter builds a multi-resolution octree that streams only what is visible.

Potree: Is my data private?

Only if you make it so. Potree serves static files with no built-in authentication, so access control is entirely your responsibility.
