> Kora is a license server you host yourself. Issue keys, check them from your products and manage customers from a web dashboard.



Kora is a license server you run on your own machine. It issues license keys for the things you sell, answers validation requests from your products and gives you a dashboard for products, customers, addons and keys.

Purchases from BuiltByBit can create and revoke licenses on their own, and customers can sign in with Discord to see their keys.
