Inkwharf vs Leanpub

Leanpub is a publishing marketplace for technical books.

Leanpub is a writing toolchain with a bookstore attached. Inkwharf is a bookstore you own, with no toolchain. If you write in Markdown and want the book built for you, stay on Leanpub. If you already have an EPUB and an audience, there is no reason to hand over a fifth of every sale — and, if you want the toolchain unthrottled, a membership on top of it.

What 20% costs a year

80% royalty at $7.99 and up; 80% minus 50¢ below it, against a subscription that does not move. Payment processing is left out of both columns — it is charged on your own Stripe account here and folded into the headline rate elsewhere, so including it would compare two different things.

$2,000/mo$4,800$228$4,572
$5,000/mo$12,000$228$11,772

Read it the other way too: below $95 a month in sales, 20% is the cheaper deal — which is what the free tier here is for, since it runs to $500 a month at 0% and costs nothing at all. Figures last checked August 2026. Run your own at the take-rate calculator.

A dot marks the side a row genuinely favours. Rows without one are a draw, and the ones marked against us are why the rest is worth reading.

Where Leanpub is the better choice

The Markdown toolchain is good, and we do not have one

Leanpub turns a folder of Markdown into a formatted PDF and EPUB on every change. That is real engineering, and it is why people put up with the rest. Inkwharf takes an EPUB you have already made — by Vellum, Sigil, pandoc, Atticus, or Leanpub itself — and does nothing whatever to produce one. If writing-to-artefact is the problem you need solved, we do not solve it.

Publish-while-writing is a real format, not a gimmick

Selling an unfinished book and shipping chapters to existing buyers works, and Leanpub built the whole product around it. Updated files reach past buyers here on the same permanent link, which covers the mechanics — but nothing on this site markets an in-progress book the way their storefront does.

Their marketplace sends traffic you did not bring

A DevOps title on Leanpub gets found by DevOps readers browsing Leanpub. That is worth something real, and it is worth precisely nothing to a novelist. If you have no list and your topic sits squarely in their niche, discovery you did not pay for is the strongest argument there is against going direct.

Where this is the better choice

Keeping 80% is paying 20%, and it never stops growing

A royalty is a percentage with better manners. At $2,000 a month of sales, 20% is $400 a month — $4,800 a year — against $228 for a subscription that does not move when you have a good year. The crossover is low and it only goes one way. Price a book under $7.99 and it is worse than 20%: the royalty becomes 80% minus 50¢, which on a $4.99 title is a 30% cut.

The toolchain is a second bill on top of the royalty

Publishing on Leanpub is free, but the free tier caps you at 20 previews a month — and previewing is how you find out what the book looks like. Unlimited previews, custom themes and print-ready PDF start at $12.99 a month, and the tier with GitHub sync and API access is $17.99. So the honest comparison for an author who actually uses the toolchain is 20% of revenue plus about $216 a year, against $228 a year and no percentage at all.

Your shop is at your address, not inside theirs

Leanpub books live on leanpub.com under Leanpub's chrome, Leanpub's URL and Leanpub's search results. A shop here resolves at your own domain, and this site's sitemap deliberately does not list author storefronts — the platform does not compete with its own sellers for their own titles.

Your reader does not need an account to buy

A sign-up wall between a fan and their book is where direct sales die. Checkout here is an email address and a card. No password, no library account, no confirmation step standing in front of the money.

The reader is not a PDF viewer from 2013

Every book gets an in-browser EPUB reader that follows the site theme, send-to-Kindle in one tap, and a free sample that is a genuine trimmed EPUB rather than a preview pane. The rest of the book is physically not inside the sample file.

It works outside software

Leanpub's model is bound to its marketplace, and its marketplace is engineers. Because there is no marketplace here, genre is irrelevant to the architecture — a romance backlist and a Kubernetes manual are the same product to this system.

Questions

Can I keep writing in Leanpub and sell here?
Yes, and for a lot of authors that is the right answer. Leanpub will export an EPUB from your Markdown; upload that file to your own shop and sell it at 0%. You keep the toolchain you like and stop paying a fifth of every sale for a storefront you do not control. Nothing here asks for exclusivity, so the book can stay on their marketplace at the same time.
Does Inkwharf build a book from Markdown?
No. This is checkout, delivery and a shop of your own — the half of the job that starts once an EPUB exists. Pandoc, Sigil, Vellum, Atticus and Leanpub itself all produce files that upload cleanly, and every upload is checked against the EPUB spec before it can go on sale.
I have no audience. Is selling direct pointless?
Not pointless, but be honest about the order of operations. A marketplace with traffic in your niche is worth a cut while you have nobody to sell to. The mistake is staying there once you do, at which point the percentage is a tax on an audience you built yourself. Opening a shop here is free, so it can sit alongside the marketplace until the numbers say otherwise.
What about the reader-sets-the-price model?
You set a price per book here; there is no pay-what-you-want slider. If variable pricing is the core of how you sell, Leanpub does it and we do not.
Isn't publishing on Leanpub free?
Publishing is, and the 20% royalty applies whether or not you subscribe. What the free tier caps is previewing — 20 a month — which is the loop you actually spend your time in while writing. Unlimited previews, custom themes and print-ready PDF start at $12.99 a month; GitHub sync and API access are $17.99. Worth knowing before comparing a royalty to a subscription, because at the top of their stack it is both.
