Add secure login and session management to your apps. SDKs available for popular languages and front-end frameworks e.g. Node.js, Go, Python, React.js, React Native, Vanilla JS, etc.

Supertokens architecture is optimized to add secure authentication for your users without compromising on user and developer experience

Three building blocks of SuperTokens architecture

1. Frontend SDK: Manages session tokens and renders login UI widgets
2. Backend SDK: Provides APIs for sign-up, sign-in, signout, session refreshing etc. Your Frontend will talk to these APIs
3. SuperTokens Core: The HTTP service for the core auth logic and database operations. This service is used by the Backend SDK

SuperTokens is an open core alternative to proprietary login providers like Auth0 or AWS Cognito. We are different because we offer:

• Open source: SuperTokens can be used for free, forever, with no limits on the number of users.
• An on-premises deployment so that you control 100% of your user data, using your own database.
• An end to end solution with login, sign ups, user and session management, without all the complexities of OAuth protocols.
• Ease of implementation and higher security.
• Extensibility: Anyone can contribute and make SuperTokens better!

Authentication directly affects UX, dev experience and security of any app. We believe that current solutions are unable to optimise for all three "pillars", leading to a large number of applications hand rolling their own auth. This not only leads to security issues, but is also a massive time drain.

We want to change that - we believe the only way is to provide a solution that has the right level of abstraction, gives you maximum control, is secure, and is simple to use - just like if you build it yourself, from scratch (minus the time to learn, build and maintain).

We also believe in the principle of least vendor lockin. Your having full control of your user's data means that you can switch away from SuperTokens without forcing your existing users to logout, reset their passwords or in the worst case, sign up again.

• Please visit our website to see the list of features.
• We want to make features as decoupled as possible. This means, you can use SuperTokens for just login, or just session management, or both. In fact, we also offer session management integrations with other login providers like Auth0.

The docs can be seen on our website.

• ✅ Whilst running Java can seem difficult, we provide the JDK along with the binary / docker image when distributing it. This makes running SuperTokens just like running any other http microservice.
• ✅ Java has a very mature ecosystem. This implies that third party libraries have been battle tested.
• ✅ Java's strong type system ensures fewer bugs and easier maintainability. This is especially important when many people are expected to work on the same project.
• ✅ Our team is most comfortable with Java and hiring for great Java developers is relatively easy as well.
• ✅ One of the biggest criticisms of Java is memory usage. We have three solutions to this:
  • The most frequent auth related operation is session verification - this happens within the backend SDK (node, python, Go) without contacting the Java core. Therefore, a single instance of the core can handle several 10s of thousands of users fairly easily.
  • We have carefully chosen our dependencies. For eg: we use an embedded tomcat server instead of a higher level web framework.
  • We also plan on using GraalVM in the future and this can reduce memory usage down by 95%!
• ✅ If you require any modifications to the auth APIs, those would need to be done on the backend SDK level (for example Node, Golang, Python..). So you’d rarely need to directly modify / work with the Java code in this repo.
