better-auth vs authentik

Better Auth is a framework-agnostic authentication and authorization library for TypeScript applications. It handles email and password sign-in, social and OAuth2 / OpenID Connect providers, sessions and two-factor authentication in your own codebase and database, rather than delegating them to a hosted identity service, and it can be extended through a plugin ecosystem.
Authentik is an open-source authentication server that provides a comprehensive solution for identity and access management. It offers a wide range of features, including multi-factor authentication, single sign-on, and user management.
