Amazon KDP
Kindle Direct Publishing — the dominant self-publishing storefront for ebooks and print-on-demand. Optional KDP Select exclusivity unlocks Kindle Unlimited. Essential for most indies; not the only store if you go wide.
PublishDrive
What it is
Wide self-publishing aggregator for ebooks, print-on-demand, and audiobooks. Subscription model: keep 100% of net store royalties and pay a flat plan fee instead of an aggregator commission cut. Competes with Draft2Digital-style workflows for authors who prefer subscription pricing and multi-format distribution from one dashboard. Always confirm current channel list and free-plan limits on the official site.
Pricing model
Subscription — Free plan for a single ebook title; paid tiers by catalog size (flat fee, 0% commission on store royalties). Always confirm on the vendor site before buying; plans change.
