Open source alternative to Auth0 / AWS Cognito / Firebase Auth
SuperTokens is building open source authentication (as an alternative to Auth0, Firebase and AWS Cognito). Add secure, hassle free authentication to your app in 1 day. We enable startups to launch quicker and focus on their core product offering 1. We're easier to implement as we take a modular approach - making it possible to pick only the features you need for your use case. This means you need not worry about complications associated with other features (eg: SSO and OAuth if you don’t need it) and this in turn makes it easier to implement and manage SuperTokens. 2. Developer's can own and manage their user's data. 3. SuperTokens can be run on your premise for free and also has a generous hosted tier for those who dont want to manage it themselves. SuperTokens is being used by hundreds of developers across the globe.
SuperTokens is an open source authentication platform that positions itself as an alternative to Auth0, AWS Cognito, and Firebase Auth. It emphasizes self-hosted control, fast setup, and reasonable pricing, with a focus on customizable authentication flows.
Provides modular authentication with prebuilt UI and frontend/back-end SDKs to implement login methods (Email/Password, Passwordless, Social login), session management, multi-tenancy, SSO, CAPTCHA protection, user banning, and customizable architecture. Offers a framework-agnostic setup that can be hosted on your domain with optional custom UI and plugins, allowing integration through recipe-based configuration across frontend and backend stacks. Includes features like tenant discovery, attack protection, and extendable plugins for security controls.
Who it’s for: startups and enterprises needing self-hosted authentication, developers building custom auth flows, teams requiring multi-tenant and SSO capabilities
