What is SuperTokens?
SuperTokens is an open-source authentication and session-management platform with frontend and backend SDKs, prebuilt login UI and support for password, passwordless, social login, MFA and multi-tenancy. Teams can run the core and their database themselves at any scale or use the managed cloud service with usage-based pricing.

COMMUNITY
From the forums
Community feedback commonly praises SuperTokens for its self-hosting model, control over user data, straightforward SDKs and helpful Discord support. The trade-offs are that self-hosting adds another core service to operate, the Java-based core is not attractive to every team, and advanced features such as MFA, account linking and multi-tenancy require careful pricing and configuration review. GitHub activity is strong, although the issue tracker still contains reports involving memory, architecture support and session behavior.
