Best Self-Publishing Platforms in 2026 (Compared for Indie Authors)

How should you compare self-publishing platforms?

Start with four questions. Which readers and stores does the platform reach? What share of each sale do you keep? Which formats does it support: ebook, paperback, hardcover, audiobook? And how much control do you keep over price, rights and your files? Cost to join matters less, because the platforms in this guide do not charge you to list a book. They take a share of each sale instead, though some print services have charged setup or revision fees in the past, so read the current fee page.

Two things are easy to overlook. First, exclusivity: some programmes, notably KDP Select, trade wide distribution for extra income and promotion tools. Second, who owns the customer relationship. On almost every retail platform the store keeps the reader data, so your own mailing list and author website are the only audience you truly own.

Royalty rates depend on price, country, format and sometimes delivery costs. A headline figure of 70% is not the same on every platform, so run your own numbers with a royalty comparison before you pick a price or a store.

Amazon KDP: best for reaching the most readers

Amazon Kindle Direct Publishing is the largest self-publishing platform and, for most genres, the biggest single source of ebook sales. Ebooks priced between $2.99 and $9.99 in the main markets earn a 70% royalty minus a small delivery fee based on file size, and 35% outside that range. Paperbacks and hardcovers pay 60% of the list price minus printing costs, with no upfront fee, and KDP can supply a free ISBN for print books published through it.

KDP also offers KDP Select, which requires your ebook to be exclusive to Amazon for each enrolment term in return for Kindle Unlimited page-read income and promotional tools. It suits some authors, especially those writing fast-reading series in genres where Kindle Unlimited readers are plentiful, and it is a poor fit for authors who want to sell wide.

The limits are about reach and control rather than quality. Bookstores and libraries rarely order from Amazon-printed titles, and you depend on one retailer's rules, algorithms and account policies. Treat KDP as essential for almost everyone, but not as your only plan.

IngramSpark: best for bookstores and libraries

IngramSpark feeds your print book into Ingram's wholesale catalogue, which bookstores, libraries and many online retailers use to order stock. You choose the wholesale discount you offer retailers and whether copies are returnable. That discount and the printing cost come out of your margin, so print royalties are thinner than on KDP, and returnable books carry real risk if a store sends copies back.

It is the standard route to bookstore and library availability, and its quality control and hardcover options are well regarded. You should supply your own ISBN rather than using a free one tied to another platform, and your files must meet its specifications exactly.

Many authors run KDP and IngramSpark side by side, using KDP for Amazon print sales and IngramSpark for everyone else. Be careful with the overlap: check the current guidance on expanded distribution so the two services do not conflict.

Draft2Digital and other aggregators: best for wide ebooks from one dashboard

An aggregator takes one upload and delivers your ebook to many stores and library services. Draft2Digital is the best-known option for indie authors. It converts a manuscript into a clean ebook, offers simple formatting templates and takes a percentage of each sale in place of any upfront fee. Check its current commission and the list of stores it reaches, because both change.

The trade-off is a slightly smaller share than going direct and one more company between you and the retailer. In return you get a single sales report, one place to update a price or description, and access to smaller stores and subscription or library services that would be time-consuming to join individually.

A common approach is a hybrid: go direct to the stores that matter most to your genre, and use an aggregator for the long tail. Be aware that you should not upload the same ebook to a store both directly and through an aggregator.

Apple Books, Kobo, Google Play and Barnes & Noble Press: which direct stores are worth it?

Apple Books reaches readers on iPhones, iPads and Macs in many countries and pays 70% of the list price on ebooks regardless of price. It supports pre-orders, and its editors feature books in collections that can drive strong sales. Kobo, through Kobo Writing Life, is particularly strong in Canada and parts of Europe and Australasia, with its own promotion tools and a subscription service. Google Play Books reaches Android users worldwide and is worth a listing mainly because setup is quick once your files are ready.

Barnes & Noble Press lets you publish ebooks and print books for the largest US bookstore chain's customers. Whether it is worth the extra account depends on your readership. Sales figures vary heavily by genre and by how much promotion you do, so test with one or two stores and see where your readers actually are.

Publishing direct gives you control over pricing, promotions and sales data, and the full retailer royalty. It also means more dashboards, tax forms and files to keep updated. Our guide on publishing wide beyond Amazon walks through that workflow, and a store-specific royalty calculator helps you compare what each store pays at your price.

Which combination of platforms should you use?

Match the mix to your goal rather than copying another author's setup. These are the most common patterns.

• Amazon only, with Kindle Unlimited: KDP with KDP Select. Simple to manage, best for fast-releasing authors in KU-heavy genres.
• Wide ebooks: KDP plus Apple Books, Kobo and Google Play, direct or through an aggregator such as Draft2Digital. Better protection from one store changing its rules.
• Print for bookstores and libraries: add IngramSpark with your own ISBN, and consider approaching local shops and libraries directly.
• Audiobooks: add an audiobook route once the ebook is stable, since narration and distribution have their own costs and terms.

Whatever you choose, keep a master copy of your files and your metadata. If you later switch strategy, for example leaving KDP Select to go wide, you will be glad you can re-upload cleanly.

Some authors prefer to avoid juggling dashboards. Browser-based platforms such as CruxOne prepare your files once and publish to Amazon KDP, Apple Books, Kobo and 50+ stores from one place, which can save time if you publish often. Whatever route you pick, confirm each store's current terms.

What mistakes should you avoid when choosing platforms?

The biggest mistake is choosing on royalty percentage alone. A lower rate in a store where your readers shop beats a higher rate in a store where you never sell. Look at where your genre sells, not at a blanket figure.

Next are metadata and ISBN muddles. Use consistent title, subtitle, author name and description everywhere, and be clear who owns the ISBN for each format, because the ISBN's publisher of record is whoever registered it. Read our guide on whether you need an ISBN before buying one.

Finally, do not forget the long game. Check your contracts and account settings for terms on exclusivity, price matching, returns and payment thresholds. Keep records for tax, since income from several countries and stores adds up. And never hand over your rights to a service that charges large fees and promises to publish your book for you. Genuine self-publishing platforms do not ask you to give up ownership.

Frequently asked questions

What is the best self-publishing platform?

For reach, Amazon KDP. Most authors then add IngramSpark for bookstores and libraries and Draft2Digital, Apple Books, Kobo or Google Play to publish wide.

Which platform pays the highest royalties?

Direct ebook stores often pay around 70%, but conditions differ. KDP pays 70% only between $2.99 and $9.99, while Apple Books pays 70% at any price.

Is it free to self-publish on these platforms?

Listing is free on the major retail platforms, which take a share of each sale instead. Check current fee pages for print services, which have charged for some services.

Can I use several platforms at once?

Yes, unless your ebook is enrolled in KDP Select, which requires Amazon exclusivity for the ebook. Print books can be sold widely at any time.

Which platform gets my book into bookstores?

IngramSpark, because bookstores and libraries mostly order through wholesale catalogues such as Ingram's. Returns and discount settings affect your margin.
