SuperTokens
Open source auth library with prebuilt UI, session management and self-hosted or managed deployment options.
Quick answer
What is SuperTokens?
Short answer
SuperTokens is an open source authentication library targeted at developers who want a drop-in auth solution without giving up control of user data. It supports email/password, social login, passwordless, MFA, session management and multi-tenancy, and can be self-hosted (often co-located with your database) or consumed as managed SaaS. It frequently appears as an Auth0 alternative for teams that prioritize self-hosting or open source.
