SuperTokens is an open-source authentication and session-management platform — a developer-friendly alternative to services like Auth0 and AWS Cognito. You can self-host it for full control or use the managed service, and either way you get customizable login, secure sessions and no vendor lock-in, across more than 25 frameworks.

What is SuperTokens?

SuperTokens handles the hard, security-critical parts of user auth so you don't have to build them from scratch: sign-up and login, session management, password policies and more. Its distinctive architecture separates a backend core from frontend SDKs, which gives developers far more room to customize flows and keep data under their control than a typical closed auth service allows.

Who it's for

SuperTokens is built for developers and teams — startups and enterprises alike — who want customizable authentication without being locked into a proprietary vendor. It's especially appealing to organizations that prefer open source, want to self-host for data ownership, or need to control auth costs as they scale. SDKs cover JavaScript, React, Angular, Vue, Python, Go, Flutter, Android, iOS and more.

Key features

• Multiple auth methods: email/password, passwordless magic links, social login and SSO
• Robust session management with custom password policies and session limits
• Multi-tenancy support with tenant discovery
• Account linking across different sign-in methods
• Attack Protection Suite with CAPTCHA integration and bot prevention
• Pre-built UI deployable in minutes, or fully custom interfaces
• Plugin system for extensibility (banning, CAPTCHA, tenant discovery)

Own your auth and your data

The biggest reason teams pick SuperTokens is control. Self-hosting means users authenticate on your own domain with no redirects to a third party, and you keep full ownership of the user data — a sharp contrast to hosted auth services. The core-plus-SDK architecture also means you can customize login flows deeply instead of bending your product around a vendor's fixed UI.

Fast to set up, deep when you need it

Despite that flexibility, SuperTokens is quick to get running: a pre-built UI can be live in about five minutes via the CLI, and 25+ framework SDKs mean it drops into most stacks. When you need more, the plugin system and customizable interfaces let you extend it — from banning users to adding CAPTCHA to building bespoke tenant discovery — so it grows with your requirements rather than capping them.

Trusted and cost-conscious

SuperTokens is Y Combinator-backed, SOC 2 compliant and has 12,000+ GitHub stars, reflecting real community trust. It also emphasizes cost savings versus commercial competitors and offers seamless migration from Auth0 without forcing password resets — so teams outgrowing a pricey hosted service can switch without disrupting their users.

Security built in, not bolted on

Authentication is where security matters most, and SuperTokens treats it that way. Its Attack Protection Suite adds CAPTCHA integration and bot prevention to defend against credential stuffing and automated abuse, robust session management guards against hijacking, and custom password policies and session limits give teams fine control over risk. Because the flows are open source, security-conscious teams can also audit exactly how their auth works rather than trusting a black box.

Why choose SuperTokens

For developers who want secure, customizable authentication without vendor lock-in or ballooning costs, SuperTokens is a compelling open-source option. Its self-hosting, flexible architecture, broad framework support, attack protection and easy migration make it a practical way to own your login stack while keeping setup fast and your users' data in your hands.
