The short version

  • Each has a real cost: DSpace self-hosting means running and maintaining the repository; managed hosting comes from third-party service providers such as Atmire, 4Science and DSpaceDirect rather than the project; Sigil it produces no print output whatever, so any book that needs a paperback interior requires a completely separate tool and a second workflow.
  • They diverge on capability: DSpace covers Self-submission workflows, Sigil covers Direct EPUB editing.
  • 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.

DSpace

  • Self-hosting means running and maintaining the repository; managed hosting comes from third-party service providers such as Atmire, 4Science and DSpaceDirect rather than the project
  • Aimed at institutional repositories, so it assumes library metadata practice rather than general file storage

Sigil

  • It produces no print output whatever, so any book that needs a paperback interior requires a completely separate tool and a second workflow.
  • Meaningful use requires reading and writing HTML and CSS, which puts it out of reach of most authors who simply want a finished file.
  • There is no cloud storage, sync or collaboration, so the book exists as a file on one machine and version control is whatever you set up yourself.
  • Development depends on a small number of volunteer maintainers, so release timing and platform builds follow their availability rather than a roadmap, and a lapse in maintenance would leave no obvious successor.
  • It provides no distribution, no retailer connection and no Kindle-native output, so it sits in the middle of a workflow that other tools have to complete on both sides.

Answered from the vendors’ own pages

DSpace: Is DSpace free to use, and what is the licensing model?

Yes, DSpace is completely free and open source under a BSD License. The software is fully customizable with no subscription fees or licensing costs required.

Source
Sigil: Can I write my book in Sigil?

You can, but you should not. It is an EPUB editor, not a word processor, and writing long-form prose in it is unpleasant. Write elsewhere, import, then finish in Sigil.

DSpace: Are there optional costs associated with using DSpace?

DSpace itself is free, but optional membership is available to support the project and advance development efforts. Voluntary contributions of any size are accepted, with benefits including event discounts and governance participation.

Source
Sigil: Does it make Kindle files?

Not natively. Produce a valid EPUB in Sigil and let Amazon convert it, or use a separate conversion tool for other Kindle formats.

DSpace: Do I need to pay for hosting and implementation services?

No, hosting and implementation are optional third-party services offered by registered DSpace providers like DSpaceDirect, 4Science, and Atmire, not requirements of the software. You can host DSpace yourself at no cost.

Source
Sigil: Is it safe to rely on a volunteer project for commercial work?

The files it produces are standard EPUB, so nothing is locked in. The risk is that maintenance stops, not that your books become unreadable.

DSpace: What languages does DSpace support?

DSpace is available in 22 languages and includes granular, group-based access control for repository management.
