Kepler.gl: If the goal is a shareable interactive visualisation rather than notebook-driven analysis
Leafmap
Python package for interactive geospatial mapping and analysis inside Jupyter notebooks
As of 1 September 2026, Leafmap is free to use. An academic open source library, not a product. Softwr lists it under Libraries. Leafmap is made by Leafmap contributors, led by Qiusheng Wu, available on Linux, Windows, macOS.
Overview
What Leafmap does
Leafmap is a Python package for interactive mapping and geospatial analysis in Jupyter notebooks. It provides a consistent API over several plotting backends including ipyleaflet, folium, MapLibre, pydeck and KeplerGL, and bundles helpers for loading vector and raster data, cloud-optimised GeoTIFFs, STAC catalogues, Earth Engine assets, basemaps and simple analysis, plus interactive widgets for drawing and inspecting layers. It exists for a specific reason. Doing interactive geospatial work in a notebook previously meant learning several unrelated libraries and writing a lot of boilerplate, and most of those libraries assume a JavaScript front end. Leafmap collapses that into a few function calls, which is why it spread quickly through university teaching, remote sensing coursework and research notebooks. It is MIT licensed with no licence fee and nothing to purchase. The project is maintained principally by Qiusheng Wu, an academic at the University of Tennessee, with contributions from the open source geospatial community and funding largely from research grants and institutional support rather than commercial revenue. That is the fact a team should weigh: Leafmap is excellent for analysis and teaching, but a single-maintainer academic package with a fast-moving API and a dependency on several third-party backends is a risky foundation for a production application with a five-year support horizon.
What people use it for
- A remote sensing course where students need interactive maps without learning JavaScript or a desktop GIS
- A researcher exploring STAC-hosted satellite imagery inside a notebook before committing to a processing pipeline
- An analyst producing a shareable interactive map from a GeoDataFrame in a handful of lines
- A team prototyping a geospatial visualisation before deciding whether to build it properly in a web framework

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about 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.

Questions people ask
Each answer names the page it came from, so you can check it rather than take our word for it.
Is Leafmap a product?
No. It is an MIT-licensed Python package installed from PyPI or conda-forge. There is nothing to purchase.
Who maintains it?
Primarily Qiusheng Wu at the University of Tennessee, with community contributors, funded through research grants rather than sales.
Can I buy support?
No commercial support offering exists. Help comes from GitHub issues and the community.
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.
