3 Best Self Publishing Platforms for Authors in 2026

When you're ready to publish, the internet will offer you a hundred platforms. In practice, indie publishing runs on three:

• Amazon KDP: for Amazon sales, where most indie books are bought
• IngramSpark: for print distribution to bookstores and libraries
• Draft2Digital: for ebooks everywhere that isn't Amazon

Here's what each one is actually for, and why the smart long-term answer is usually "more than one."

1. Amazon KDP: where the readers already are

KDP is where most self-published authors start, and where many make the majority of their sales, for a simple reason: the readers are already on Amazon.

It's free to publish, beginner-friendly, and fast: you upload your manuscript and cover, set a price, and your book can be live on Amazon stores worldwide within days. It handles Kindle ebooks, paperbacks and hardcovers, printed on demand so you never hold stock.

Best for: your first book, Kindle readers, and reaching the biggest online bookstore on Earth with the least friction.

The trade-off: KDP is Amazon-centred. It puts you on Amazon brilliantly; it does very little to put you anywhere else.

One small KDP headache worth knowing in advance: if your paperback and ebook show up as two separate Amazon pages, it's usually a tiny metadata mismatch, and it's fixable.

2. IngramSpark: the door to bookstores and libraries

Ingram is the wholesale distributor most bookstores and libraries already order from, which means a book on IngramSpark is orderable by thousands of physical stores, libraries and international retailers.

That's the difference between the two print platforms in one sentence: KDP puts your book on Amazon; IngramSpark makes it available to everyone else.

It's less beginner-friendly: there are wholesale discounts and return settings to understand, and the dashboard assumes some publishing knowledge. It's also often preferred for premium formats: hardcovers, illustrated books, higher-end finishes.

Best for: authors who want bookstore and library availability, premium print options, or wide global distribution.

3. Draft2Digital: every ebook store that isn't Amazon

Apple Books, Kobo, Barnes & Noble, library ebook apps: together they're a meaningful slice of ebook reading, and reaching each one individually is tedious.

Draft2Digital solves that: upload once, and it distributes your ebook to all of them, with clean automatic formatting and one sales dashboard. There's a one-time $20 activation fee, then it takes about 10% of the retail price of each sale, plus $12 a year if your account earns under $100 a year (Draft2Digital's FAQ).

Best for: getting your ebook "wide" with almost no extra work. (Its automatic formatting covers the ebook. For a paperback you'll want a proper file, and these formatting tools are the ones worth comparing.)

Why using all three is the smart play

Plenty of authors run everything through one platform. It works, right up until it doesn't.

If your single platform has a technical issue, a listing problem, or an account restriction, your entire book business stops with it. Spread across three, a problem at one costs you one channel, not your livelihood.

The combination most indie authors settle on:

• KDP for Amazon (ebook + paperback)
• IngramSpark for print everywhere else
• Draft2Digital for ebooks everywhere else

One book, three doors, no single point of failure.

Going wide has one trade-off to weigh first: an ebook that's on other stores can't be in KDP Select, so it isn't in Kindle Unlimited. KDP Select vs going wide sets out when exclusivity pays and when it doesn't.

(One practical note if you plan to combine KDP and IngramSpark for print: use your own ISBN rather than a platform's free one, so the same edition can live on both. Here's the full ISBN decision explained.)

Start simple, widen later

You don't need to master all three on day one. A perfectly good sequence:

1. Publish on KDP and learn the basics
2. Add Draft2Digital when you want your ebook everywhere
3. Add IngramSpark when print-in-bookstores starts to matter to you

For a deeper head-to-head on the two print platforms (royalties, print quality, distribution), read KDP vs IngramSpark: which should you choose?. And for what all of this costs in practice, see the real cost of self-publishing.

Long-term, depending on a single platform is never the safest strategy. But don't let platform strategy delay the only thing that actually matters: getting your book into the world.
