The short version

  • Only Leafmap has a free tier, so it costs nothing to try first.
  • Each has a real cost: Kepler.gl kepler.gl is a free open source library with no vendor-sold edition; confirmed by the absence of any App Store, marketplace or G-Cloud listing, support is limited to community GitHub issues rather than a purchased SLA.; Leafmap it is a Python library rather than an application, so there is nothing to buy, nothing to install for a non-technical colleague and no interface outside a notebook environment.
  • They diverge on capability: Kepler.gl covers Core Functionality, Leafmap covers Multiple mapping backends.
  • Prices and features above were last checked on 1 September 2026.

No use cases recorded yet. See the Kepler.gl review.

Leafmap

  • A remote sensing course where students need interactive maps without learning JavaScript or a desktop GISnot Kepler.gl
  • A researcher exploring STAC-hosted satellite imagery inside a notebook before committing to a processing pipelinenot Kepler.gl
  • An analyst producing a shareable interactive map from a GeoDataFrame in a handful of linesnot Kepler.gl
  • A team prototyping a geospatial visualisation before deciding whether to build it properly in a web frameworknot Kepler.gl

Where each one falls short

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

Kepler.gl

  • Kepler.gl is a free open source library with no vendor-sold edition; confirmed by the absence of any App Store, marketplace or G-Cloud listing, support is limited to community GitHub issues rather than a purchased SLA.

Leafmap

  • It is a Python library rather than an application, so there is nothing to buy, nothing to install for a non-technical colleague and no interface outside a notebook environment.
  • Maintenance rests largely on one academic maintainer with grant funding, which makes long-term continuity a real consideration for anything beyond research use.
  • The API has moved quickly across releases, so notebooks written against an older version can break on upgrade, which undermines reproducibility in exactly the research settings where it is popular.
  • It abstracts over several third-party backends, so a bug or a rendering limitation is often in ipyleaflet, folium or MapLibre rather than in Leafmap, and diagnosing it means understanding the layer underneath anyway.
  • Large datasets rendered through notebook widgets become slow or unresponsive, so it does not scale to the data volumes a dedicated tiling service or desktop GIS handles comfortably.

Answered from the vendors’ own pages

Leafmap: Is Leafmap a product?

No. It is an MIT-licensed Python package installed from PyPI or conda-forge. There is nothing to purchase.

Leafmap: Who maintains it?

Primarily Qiusheng Wu at the University of Tennessee, with community contributors, funded through research grants rather than sales.

Leafmap: Can I buy support?

No commercial support offering exists. Help comes from GitHub issues and the community.

Leafmap: Is it suitable for a production web application?

It is not designed for that. Use it for analysis and prototyping, then build production maps on MapLibre, deck.gl or a hosted service.
