The short version

  • Each has a real cost: digiKam raw conversion quality is behind Lightroom, Capture One and DxO PhotoLab, so most users treat digiKam as a catalogue and develop files in a second application.; 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: digiKam covers Catalogue database, Pressbooks covers Single source, three outputs.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

digiKam

  • Raw conversion quality is behind Lightroom, Capture One and DxO PhotoLab, so most users treat digiKam as a catalogue and develop files in a second application.
  • The interface exposes an enormous number of options across crowded panels, and new users routinely fail to find basic functions without reading the manual.
  • Libraries beyond roughly one hundred thousand images need deliberate maintenance of thumbnails and the database, and the SQLite backend slows noticeably before the MySQL one becomes worth configuring.
  • The Windows and macOS builds receive less testing than Linux, and crashes and packaging problems on those platforms are resolved more slowly.
  • There is no commercial support contract, no client delivery and no cloud sync, so an organisation adopting it accepts that its own staff are the support line.

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

digiKam: Can several people use one digiKam catalogue?

Yes, by pointing digiKam at a shared MySQL or MariaDB database with images on a network volume. It is not designed for simultaneous heavy editing but it works for shared cataloguing.

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.

digiKam: Does it move or change my files?

Not unless you ask. It catalogues folders in place, and metadata can be written to sidecar files rather than into the originals.

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.

digiKam: Is it a Lightroom replacement?

As a catalogue, yes. As a raw developer, no. Most people who switch pair it with darktable or RawTherapee for editing.

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.
