leafmap review
A free Python library for notebook-based mapping, spatial analysis, and web apps.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Leafmap is a free, open-source Python library for interactive mapping and geospatial analysis in Jupyter environments. Researchers, geospatial data scientists, developers, and notebook-oriented learners can use it to display and edit vector data, visualize rasters, explore tiled services, and create map visualizations. It is a library rather than a hosted SaaS product, so it fits teams building geospatial workflows in Python better than buyers looking for a turnkey mapping service.
Its breadth is a defining strength: leafmap supports mapping backends including ipyleaflet, folium, kepler.gl, pydeck, and bokeh, alongside GeoPandas, PostGIS, and STAC integrations. Features span choropleths, heat maps, time-series visualization, raster pixel inspection, and WhiteboxTools-based analysis. That range can support varied notebook tasks, but also makes the project more developer-oriented than a focused point-and-click GIS. Users should be comfortable selecting tools and working in a coding environment.
Leafmap also extends beyond notebooks, with interactive web-app development through Voila, Streamlit, and Solara, plus MapLibre dashboard and 3D mapping examples. The published deployment options include cloud and self-hosted use, while support channels are documentation and community. These options suit people who want to carry notebook maps into lightweight applications, but organizations seeking a packaged SaaS with dedicated support should consider a different kind of product. Choose leafmap for flexible Python-based geospatial visualization and analysis; look elsewhere if a managed, non-code GIS is the priority.
leafmap pros and cons
- Where it wins
- Supports several mapping backends, including ipyleaflet, folium, and kepler.gl
- Visualizes and edits vector data, and displays raster and GeoTIFF data
- Connects notebook maps with WhiteboxTools, STAC, and web-app frameworks
- Where it doesn't
- Requires a Python and Jupyter-oriented workflow
- Combines many backends, so users must choose a mapping approach
- Docs and community are the listed support channels
