Key differences
- supertokens-core provides core authentication logic and database operations, while AuthKit demonstrates how to connect an application to WorkOS User Management.
- supertokens-core supports several login flows and features including session management, multi-factor authentication, roles, and tenant support; AuthKit focuses on hosted or custom login UI examples, OAuth callbacks, and an SSO callback example.
- supertokens-core can be deployed on-premises with user data in the operator's database; AuthKit relies on WorkOS and requires account credentials and configured redirect URLs.
- supertokens-core is written in Java and reports its license as NOASSERTION; AuthKit is written in TypeScript and is licensed under MIT.
- supertokens-core's repository is the core service within a broader SDK-based system; AuthKit is an implementation reference rather than a standalone authentication service.
- AuthKit's repository indicates no tests or CI and no release in the past year; supertokens-core's provided project details identify it as unarchived.
