Overview and Architecture

SuperTokens provides an open source user authentication architecture designed for developers to build fast while retaining full data ownership (https://supertokens.com).

SuperTokens architecture consists of three building blocks: a Frontend SDK for session management and UI, a Backend SDK providing auth APIs, and the SuperTokens Core HTTP service handling core authentication logic and database operations. This separation ensures that frontend clients interact with application backend endpoints, while the backend orchestrates calls to the core service.

SuperTokens is an open-core alternative to proprietary login providers like Auth0 or AWS Cognito that allows on-premises deployment to maintain full control of user data.

Supported Authentication Features

Supported authentication features include passwordless login, social login, email password authentication, session management, multi-factor authentication, and multi-tenancy enterprise SSO.

Configuration

The SuperTokens core service configuration establishes default network listening on port 3567 with access token validity configured in seconds:

yaml
1core_config_version: 0

SuperTokens core source code is distributed under the Apache License Version 2.0. This permissive licensing model allows teams to inspect, modify, and integrate core capabilities without proprietary restrictions.
