The short version

  • Each has a real cost: 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.; Pressbooks self-hosting is free in licence terms only; it requires WordPress multisite administration, upgrades and backups, which is a real staff cost most institutions underestimate.
  • They diverge on capability: Leafmap covers Multiple mapping backends, Pressbooks covers Single source, three outputs.
  • 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.

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.

Pressbooks

  • Self-hosting is free in licence terms only; it requires WordPress multisite administration, upgrades and backups, which is a real staff cost most institutions underestimate.
  • Professional print PDF output depends on a commercial rendering engine that is licensed separately, so the genuinely free self-hosted route produces web and EPUB output but not press-quality print.
  • Design control is limited to the supplied themes unless someone writes custom CSS, so books tend to look recognisably like Pressbooks books.
  • There is no distribution, no ISBN service and no retail channel, so it produces files and web pages but plays no part in selling anything.
  • The editing experience inherits WordPress conventions, and authors working on long or heavily structured manuscripts find it slower than a dedicated writing application.

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.

Pressbooks: Is Pressbooks really free?

The software is GPL licensed and free to self-host. The hosted service is priced, and professional print PDF output requires a commercially licensed renderer, so budget accordingly.

Leafmap: Who maintains it?

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

Pressbooks: Can I sell a book made in Pressbooks?

You can sell the EPUB or the printed book through any distributor, but Pressbooks itself provides no ISBN, no storefront and no distribution.

Leafmap: Can I buy support?

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

Pressbooks: Why do universities use it for open textbooks?

Because an openly licensed book can be cloned into another institution network and adapted for a different course, which turns a finished textbook into a starting point rather than a fixed artefact.

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.
