Where each one falls short

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

ArchivesSpace

  • Requires Java 17 or 21 (or Java 11/17 for older versions), adding infrastructure complexity
  • Mandatory Solr 9 (or 8 for older versions) for all production deployments since v3.2.0
  • Production deployments must use external MySQL 5.x or 8.x; embedded database only for testing
  • Minimum 1 GB RAM required, 2 GB recommended; Docker installation recommended as of v4.0.0 due to complexity

Calibre

  • The interface is dense and widely described as unintuitive, with a great deal exposed at once
  • Conversion between formats is imperfect, and complex layouts degrade
  • Cannot remove DRM, so purchased books from most stores will not convert without third-party plugins
  • Heavy for someone who only wants to read rather than manage a library
