Is Lonboard or Potree better?

Neither clearly leads. Lonboard starts at Free and Potree at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Lonboard or Potree?

Lonboard starts at Free and Potree at Free.

Does Lonboard or Potree run on more platforms?

Lonboard runs on Linux, macOS, Windows. Potree runs on Web, Windows, macOS, Linux.

Can I use Lonboard for free?

Both have a free tier, so you can try either at no cost before committing.

What is Lonboard best used for?

Lonboard is most often used for an analyst exploring a national road or parcel dataset in a notebook where pydeck or ipyleaflet becomes unusable at that size, a researcher publishing a reproducible analysis where the visualisation must run from the same script as the processing, a data scientist joining spatial data to model outputs in pandas and needing to see the result immediately without exporting to a gis, a team building an internal analysis pipeline on geoparquet that wants rendering without a serialisation step in the middle. Of those, an analyst exploring a national road or parcel dataset in a notebook where pydeck or ipyleaflet becomes unusable at that size and a researcher publishing a reproducible analysis where the visualisation must run from the same script as the processing are not what Potree is typically brought in for.

What can Lonboard do that Potree cannot?

Lonboard covers GeoArrow binary transfer, GeoPandas input, deck.gl layers, Jupyter widget. Potree covers Octree streaming, Large dataset rendering, Measurement tools, Clipping and profiles.

The short version

Each has a real cost: Lonboard it is a notebook visualisation library, not a mapping application, so there is no editing, no layout, no map export for print and no sharing beyond distributing the notebook or an HTML file; 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: Lonboard covers GeoArrow binary transfer, Potree covers Octree streaming.

Where each one falls short

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

Lonboard

It is a notebook visualisation library, not a mapping application, so there is no editing, no layout, no map export for print and no sharing beyond distributing the notebook or an HTML file
Maintenance sits with Development Seed as an open source side output of a consultancy, so roadmap priorities follow client projects and there is no support contract to buy
Layer coverage is a subset of deck.gl, so an analyst needing a less common layer type has to drop to pydeck or write JavaScript rather than staying in Python
It expects data already in GeoPandas or Arrow form, which means the performance benefit depends on the rest of your pipeline being Arrow-friendly; reading a large Shapefile is still the slow step
Rendering happens in the browser, so very large datasets are ultimately limited by the client machine's memory and GPU rather than by the server, and a laptop will still fail on data a workstation handles

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

Lonboard: Why not just use pydeck?

pydeck serialises geometry to GeoJSON to reach the browser. Lonboard uses a binary GeoArrow pipeline, which is the reason it handles far larger datasets in the same notebook.

Potree: Does Potree cost anything?

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

Lonboard: Who maintains it?

Development Seed, a geospatial engineering consultancy, as an open source project. There is no commercial support offering.

Potree: Is there commercial support?

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

Lonboard: Does it work outside Jupyter?

It is built as a Jupyter widget. Exporting to standalone HTML is possible, but the intended environment is a notebook.

Potree: Who maintains it?

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

Lonboard: Is it free for commercial use?

Yes, it is open source with no licence fee.

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.
