Best App Marketplaces
Verified platform marketplaces that distribute applications and extensions to an existing customer base.
Introduction
A platform marketplace is distribution rather than discovery. The audience is already using the host product, and a listing puts an application in front of them at the moment they are looking to extend it. That is a materially better position than a general directory, and it is why marketplace listings are usually gated.
The cost is lock-in to the host platform's rules, review process and commercial terms, few of which are published openly.
Evidence base
Evidence base: 9 of 64 verified directories in the PetroHrys dataset are platform app marketplaces. Every figure and table on this page is generated from those records at build time. Fields that were never established are shown as Unknown rather than filled in.
Who should use these
Software vendors building on an established platform: ecommerce, CRM, collaboration or developer tooling.

How to read this list
Expect a review process and budget time for it. Marketplace listing pricing is unpublished for most entries in this dataset, so treat cost as an unknown to be confirmed with the platform rather than assumed.
Frequently asked questions
Do marketplaces charge to list?
Most in this dataset do not publish listing pricing, so the submission model is recorded as Unknown. Several take a revenue share on sales, which is a separate question from a listing fee.
