The short version

  • Each has a real cost: CKAN the package install path requires Ubuntu 20.04 or 22.04 64-bit specifically; other operating systems must use the source install; 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: CKAN covers Dataset Management, Potree covers Octree streaming.
  • 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.

CKAN

  • The package install path requires Ubuntu 20.04 or 22.04 64-bit specifically; other operating systems must use the source install
  • Only Solr 9 and Solr 8 are supported, and from CKAN 2.10 they are the only Solr versions supported at all
  • A working deployment requires PostgreSQL, Solr, Redis, nginx, supervisor and uWSGI to be installed and maintained separately
  • Python 3.10 or later is required

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

CKAN: Is CKAN open-source and what license is it available under?

Yes, CKAN is an open-source data management system built on Python and available on GitHub. The license terms are available on their GitHub repository.

Source
Potree: Does Potree cost anything?

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

CKAN: Does CKAN offer commercial support for organizations?

Yes, CKAN offers commercial support through certified providers including Link Digital and Datopian. Support includes advisory services, application development, integration, managed hosting, and web development.

Source
Potree: Is there commercial support?

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

CKAN: Who is responsible for hosting costs when running CKAN?

Organizations deploying CKAN are responsible for their own hosting infrastructure. Commercial providers like Datopian and Link Digital offer managed hosting services if organizations prefer not to self-host.

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.
