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.

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. It's free to use — the platform takes a small share of each sale instead.

Best for: getting your ebook "wide" with almost no extra work.

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.

(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.
