The short version

  • Each has a real cost: Cesium ion streaming is metered in gigabytes a month, so a public-facing application's cost is driven by visitor traffic you do not control, and a successful launch can blow through a tier immediately.; 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.
  • They diverge on capability: Cesium ion covers 3D Tiles tiling, Potree covers Octree streaming.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Cesium ion

  • A simulation team streaming global terrain and imagery into an Unreal Engine environmentnot Potree
  • An urban planning department publishing a city model that planners can inspect without desktop GIS softwarenot Potree
  • A software product embedding 3D geospatial views and needing hosted tiling rather than building a tilernot Potree

Potree

  • A drone survey firm delivering a point cloud to a client who has no desktop software, by publishing a browser viewer link instead of a 40 GB LAZ filenot Cesium ion
  • A heritage or archaeology project publishing a scanned site for public access without paying per-gigabyte hosting to a commercial platformnot Cesium ion
  • An engineering consultancy embedding a point cloud viewer inside its own client portal without licensing a commercial web viewernot Cesium ion
  • A university or research group that needs measurement and profiling in a shareable viewer for a dataset too large to emailnot Cesium ion

Where each one falls short

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

Cesium ion

  • Streaming is metered in gigabytes a month, so a public-facing application's cost is driven by visitor traffic you do not control, and a successful launch can blow through a tier immediately.
  • Reality modelling is billed in gigapixels a month, an unfamiliar unit that makes it hard to estimate in advance how many drone flights a plan will actually cover.
  • The free Community tier is restricted to non-commercial or open use, so a consultancy sharing a model with a paying client does not qualify regardless of how small the dataset is.
  • Team accounts cost substantially more than individual ones at the same quota, $524 against $149 on Commercial, so adding a second colleague is a large step rather than an incremental seat charge.
  • Self-hosting is available only under a custom enterprise agreement, which leaves organisations with data residency or air-gap requirements out of the published tiers entirely.

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

Cesium ion: How is Cesium ion priced?

By several meters at once: storage in gigabytes, streaming in gigabytes per month, and reality modelling in gigapixels per month. Commercial starts at $149 a month for an individual.

Potree: Does Potree cost anything?

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

Cesium ion: Is the free tier usable commercially?

No. Community is for non-commercial or open use. Commercial work needs a paid plan.

Potree: Is there commercial support?

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

Cesium ion: Can I run ion on my own infrastructure?

Only under a custom enterprise agreement negotiated with Cesium.

Potree: Who maintains it?

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

Cesium ion: Do I need Cesium ion to use CesiumJS?

No. CesiumJS is open source and free. ion provides hosted tiling, base layers and streaming that you would otherwise have to build.

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.
