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; Navmii GPS pricing is pay-as-you-go but no rate cards or costs published online
  • They diverge on capability: Lonboard covers GeoArrow binary transfer, Navmii GPS covers Offline navigation.
  • 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.

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

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 Navmii GPS is typically brought in for.
What can Lonboard do that Navmii GPS cannot?
Lonboard covers GeoArrow binary transfer, GeoPandas input, deck.gl layers, Jupyter widget. Navmii GPS covers Offline navigation, Voice guidance, Speed camera alerts, Traffic updates.

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.

Navmii GPS: How is Navmii GPS pricing structured?

Navmii uses a pay-as-you-go model where you only pay for what you actually use, avoiding fixed contracts or capacity planning limitations. However, specific rates and pricing details are not published online. Source: https://www.navmii.com/pricing

Lonboard: Who maintains it?

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

Navmii GPS: How do I get Navmii pricing information?

Navmii pricing requires direct contact with their sales team. You can call +44 (0)208 090 8311, email [email protected], or use their online contact form. Specific pricing details are customized based on your integration and usage needs. Source: https://www.navmii.com/pricing
