RBAC, session management and user management dashboard are open source too. Its several years of an engineering team's work that is all open source.
Our philosophy is to keep features that are broadly required by developers and small companies in the open source version. Things that large companies require, will be source available.
We have several enterprises (more than $100M raised or several hundred employees) that are using SuperTokens at the scale of millions of monthly active users - all using the open source product. We think the open source product is a sufficient alternative (for a large enough population).
Are there any other features you feel should be in the open source version? Happy to hear any feedback and improve
