  • They diverge on capability: FOLIO covers Modular app architecture, Pressbooks covers Single source, three outputs.

Where each one falls short

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

FOLIO

  • FOLIO is open source with no vendor-run SaaS from the FOLIO project itself; adopters must self-host or contract a third-party hosting partner separately.

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.
