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; TomTom free app lacks specific feature details on landing page
  • They diverge on capability: Lonboard covers GeoArrow binary transfer, TomTom covers Core Functionality.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

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

TomTom

  • Free app lacks specific feature details on landing page
  • Monetization model not transparent
  • No published pricing for premium features
  • No information about subscription tiers or in-app purchases

Questions people ask

Is Lonboard or TomTom better?
Neither clearly leads. Lonboard starts at Free and TomTom at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Lonboard or TomTom?
Lonboard starts at Free and TomTom at Free.
Does Lonboard or TomTom run on more platforms?
Lonboard runs on Linux, macOS, Windows. TomTom runs on iOS, Android.
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 TomTom is typically brought in for.
What can Lonboard do that TomTom cannot?
Lonboard covers GeoArrow binary transfer, GeoPandas input, deck.gl layers, Jupyter widget. TomTom covers Core Functionality, User Interface.

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.

TomTom: Is the TomTom app free to download and use?

Yes, the TomTom app is available as a free download. The page states 'Download for free' with no mention of paid tiers on the landing page.

Source
Lonboard: Who maintains it?

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

TomTom: Are there paid features or premium tiers for TomTom?

The landing page does not disclose any pricing information for premium features or subscription tiers. Users must download the app to discover any in-app monetization details.

Source
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.

Lonboard: Is it free for commercial use?

Yes, it is open source with no licence fee.
