Pressbooks: sovereignty score and 8 European alternatives

Pressbooks is a platform for writing, formatting and publishing books. It is built on WordPress Multisite and exports to formats such as EPUB, PDF and several XML flavours, as well as publishing on the web. Self-publishing authors, publishers and educational institutions use it for books and open learning materials. Pressbooks is available as a hosted service for individual books, as a managed network for organisations, or as software you install yourself. It is an alternative to closed book-formatting tools such as Vellum or Atticus.

Pressbooks is developed by Book Oven Inc., a company based in Montreal, Canada, outside the EU. In its privacy policy the company refers to the EU GDPR, the UK GDPR and Canada's PIPEDA, among others. The company does not state where the hosted data is stored. The software is open source under GPL-3.0 or later, so you can also run Pressbooks on your own infrastructure or with an EU hosting provider of your choice.

Why digital sovereignty matters with Pressbooks

Pressbooks is headquartered in CA, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Pressbooks hosts data outside the EU (OTHER). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Pressbooks is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Pressbooks together with your other vendors and gives a total score, a heatmap and the main risk drivers.
