The short version
- Each has a real cost: Sigil it produces no print output whatever, so any book that needs a paperback interior requires a completely separate tool and a second workflow.; Webtoon the Canvas open-publishing tier is largely unpaid or very low-paid for the vast majority of creators, and building a paying audience without an existing platform boost or promotion is difficult, so most work on the platform earns its creator little to nothing.
- They diverge on capability: Sigil covers Direct EPUB editing, Webtoon covers Vertical-scroll format.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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.
Webtoon
- The Canvas open-publishing tier is largely unpaid or very low-paid for the vast majority of creators, and building a paying audience without an existing platform boost or promotion is difficult, so most work on the platform earns its creator little to nothing.
- Fast Pass early access is a real-money coin purchase per chapter, and following several ongoing popular series can add up in cost for a reader who consistently wants to read ahead rather than wait.
- Coin pack pricing is structured so that unlocking a handful of chapters regularly across multiple series costs meaningfully more than a flat subscription would, and the per-chapter cost is not always transparent before purchase.
- Only a limited number of creators are accepted into the paid Originals programme, so the promise of making a living from Webtoon publishing applies to a small fraction of contributors rather than the broader creator base.
- As with Wattpad under the same Naver ownership, product direction is set within a larger conglomerate strategy, and Canvas creators in particular have limited leverage or support compared with the curated Originals slate.

Answered from the vendors’ own pages
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.
Webtoon: Do I have to pay to read Webtoon comics?
No, chapters become free after a delay; paying with Webtoon Coins through Fast Pass only lets you read upcoming chapters early.
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.
Webtoon: Can Canvas creators get paid?
Direct payment on Canvas is limited; most paid creator opportunities come through being accepted into the curated Originals programme.
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.
Webtoon: Who owns Webtoon?
Webtoon Entertainment, owned by Naver, the South Korean internet company that also owns Wattpad.
