  • If your company currently makes more than $50K in annual gross revenues or has raised funds in excess of $50K
  • If you are working on a government project
  • If you are working on funded educational research
  • If you exceed the usage limits of the free Community account

The free Community account can be used for

  • Non-commercial personal projects
  • Exploratory commercial or government development, e.g., evaluating if Cesium ion will meet your needs

If you are not sure if you need a free or paid account, just ask tim@cesium.com.

How are apps & end users counted?

All Cesium ion plans have no limit to the number of apps and end users for your apps. You can build as many CesiumJS applications as you would like that use the same Cesium ion account for streaming 3D assets. There is also no limit to the number of unique end users that utilize your apps.

All of usage generated by your apps and end users just need to fit into the usage limits of your Cesium ion account.

What is the Storage (GB) limit?

Storage is only counted for source assets that you upload to Cesium ion, e.g., if you upload terrain or imagery that Cesium ion tiles for streaming to CesiumJS Storage is computed using the source asset size, not the generally larger size after tiling.

Assets already included in Cesium ion such as Cesium World Terrain and Sentinel-2 Imagery do not count toward the Storage limit.

What is the Bing Maps Sessions limit?

Loosely, a session is defined by loading a CesiumJS app, creating a new CesiumJS window, or selecting Bing Maps imagery in a CesiumJS app using the Imagery Selector Widget.

Precisely, a session is defined by a call to Cesium.createWorldImagery in CesiumJS, which happens when Cesium.Viewer is created.

Cesium ion’s default imagery is provided by Microsoft Bing Maps so it does not count toward your ion Data Streaming limit. You do not need a separate Bing Maps account.

If you need to reduce your session usage, consider using the Sentinel-2 Imagery tileset, a lower-resolution tileset that only counts towards your Data Streaming limit. This may be especially useful for development use and unit tests.

What is the Data Streaming (GB / month) limit?

Data Streaming is computed as the total data downloaded, e.g., streamed, from 3D assets in your Cesium ion account in a month. This includes assets you upload as well as assets included in Cesium ion such as Cesium World Terrain and Sentinel-2 Imagery.

Bing Maps usage does not count toward your Data Streaming limit; it only counts toward your Bing Maps Sessions limit.

For example, a CesiumJS app that zooms in close to the Grand Canyon and pans throughout the area may stream 25 MB from Cesium World Terrain. Test your scenarios with a tool such as Chrome DevTools Network tab.

Data Streaming does not include downloading source assets.

What if my Cesium ion account goes over one of the limits?

If you try to upload an asset that would make your account exceed the Storage limit, the user interface lets you know.

We work with "soft limits" for Data Streaming. This means we will continue to stream data to your account even if it exceeds the monthly Data Streaming limit. But we ask that you monitor your usage (which can be done from within your ion account under Usage) and make plans to upgrade to the next highest tier once you start exceeding the monthly Data Streaming limit. Repetitive excess usage and/or extreme overage without taking action to upgrade could result in our need to take action to stop streaming.

Where do I go for support?

If you have a free Community Cesium ion account, check out the Cesium forum , where the Cesium developer team hangs out, or submit an issue to the Cesium ion GitHub repo , especially if you are reporting a bug or requesting a new feature.

If you have a paid commercial Cesium ion account, feel free to use the public forum or GitHub links above, especially if your question may help other users. If you need to or prefer to keep your question private, send us an email.
