  • They diverge on capability: CesiumJS covers Core Functionality, Potree covers Octree streaming.

Where each one falls short

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

CesiumJS

  • The free Community tier does not permit commercial use
  • The cheapest commercial plan is $149 a month for an individual and $524 for a team
  • Team accounts are capped at 5 members on both the Commercial and Premium plans
  • Three separate quotas apply at once, being storage, monthly streaming and monthly reality modelling gigapixels, and exceeding any one of them constrains the account
  • Streaming is capped at 15 GB a month on the free tier

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.

Answered from the vendors’ own pages

CesiumJS: Is Cesium ion free for commercial use?

Cesium offers a free Cesium ion community account, but the page does not explicitly state whether the free tier is permitted for commercial use or if restrictions apply to business applications.

Source
Potree: Does Potree cost anything?

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

CesiumJS: What are the limits of the free Cesium ion community account?

The page only mentions that a free community account is available but does not disclose usage limits, storage quotas, or feature restrictions for the free tier.

Source
Potree: Is there commercial support?

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

CesiumJS: What do paid Cesium ion tiers cost?

The page does not provide specific pricing for paid tiers. It directs users to sign up for a free community account or contact Cesium directly for detailed pricing information.

Source
Potree: Who maintains it?

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

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.
