Public integration app marketplaces
Platforms with a standard OAuth app plus a basic marketplace listing and moderate compliance.
21 marketplaces in this directory match this tag.
A public integration is the middle tier of build complexity: a multi-tenant OAuth app plus a basic marketplace listing and moderate compliance. Any customer can install it, but you are not held to the deep UI standards or heavy certification of a full marketplace app.
It is the sweet spot for most SaaS vendors adding a connector or a light embedded surface — enough process to be trusted and discoverable, without the multi-week review of enterprise stores. Expect OAuth, scoped permissions, and a functional review before listing.
