The short version

  • Only Lonboard has a free tier, so it costs nothing to try first.
  • 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; Radar no free tier available
  • They diverge on capability: Lonboard covers GeoArrow binary transfer, Radar covers Core Functionality.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Lonboard

  • A data scientist joining spatial data to model outputs in pandas and needing to see the result immediately without exporting to a GISnot Radar
  • A team building an internal analysis pipeline on GeoParquet that wants rendering without a serialisation step in the middlenot Radar

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

Radar

  • No free tier available
  • Annual contracts required with committed monthly quotas
  • Volume discounts applied manually; no public discount tiers

Questions people ask

Is Lonboard or Radar better?
Neither clearly leads. Lonboard starts at Free and Radar at $0.02/per monthly tracked user, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Lonboard or Radar?
Lonboard has a free tier; the other does not. Paid plans start at Free for Lonboard and $0.02/per monthly tracked user for Radar.
Does Lonboard or Radar run on more platforms?
Lonboard runs on Linux, macOS, Windows. Radar runs on iOS, Android, Web.
Can I use Lonboard for free?
Yes. Lonboard has a free tier, so you can try it without paying. Radar starts at $0.02/per monthly tracked user.
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 Radar is typically brought in for.
What can Lonboard do that Radar cannot?
Lonboard covers GeoArrow binary transfer, GeoPandas input, deck.gl layers, Jupyter widget. Radar 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.

Radar: What is Radar's core function?

Radar is an all-in-one location platform providing SDKs and APIs for geofencing, trip tracking, geocoding, and location search. It handles 100+ billion annual queries from 100+ million devices.

Source
Lonboard: Who maintains it?

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

Radar: Who uses Radar?

Companies like Sleeper, Panera, DICK's Sporting Goods, T-Mobile, and Zillow use Radar's geofencing SDKs and maps APIs for location-based solutions.

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.

Radar: How is Radar's pricing structured?

Radar does not publicly disclose pricing. Custom quotes are required based on usage and requirements, meaning pricing varies per customer.

Source
Lonboard: Is it free for commercial use?

Yes, it is open source with no licence fee.

Radar: What are Radar's security and privacy features?

Radar prioritizes enterprise-level security, privacy, and customer support. It maintains high uptime, low latency connections for reliable monitoring of location data across platforms.
