- Each has a real cost: Lulu no fixed pricing published; vendor requires pricing calculator for quotes; Sigil it produces no print output whatever, so any book that needs a paperback interior requires a completely separate tool and a second workflow.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Lulu
- No fixed pricing published; vendor requires pricing calculator for quotes
- Costs vary significantly based on trim size, binding type, page count, and shipping
- Author royalties and distribution fees not disclosed on website
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
Lulu: How much does Lulu self-publishing cost?
Lulu does not publish fixed pricing. Costs depend on specific book specifications including trim size, binding type, page count, and distribution format. Users must access Lulu's pricing calculator to receive personalized quotes for their book project.
SourceSigil: 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.
Lulu: How does Lulu's pricing calculator work?
Users input their book specifications such as trim size, binding type, and page count into Lulu's pricing calculator tool to receive customized pricing quotes and view production timelines.
SourceSigil: 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.
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.
