Our standard licenses don’t allow for redistribution. Therefore, if you want to redistribute Duende IdentityServer as part of a product to your customers, you'll need a redistribution license.
The redistribution license is bound to a product you create and allows for both self-hosting (SaaS, or on behalf of your customers), as well as redistribution to a customer’s on-premises or cloud infrastructure (or combinations of that).
For every redistribution package, you can either purchase a license for a fixed number of client applications, or for an unlimited number of client applications for more flexibility and support.
