better-auth vs Clerk
Side-by-side comparison of features, pricing, ratings, and alternatives.
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.
Clerk provides a complete authentication and user management solution that lets developers add sign‑in, sign‑up, and profile flows with just a few lines of code. Its prebuilt UI components are customizable and work out‑of‑the‑box, reducing the time spent building secure login experiences. The platform also offers a robust API and SDKs for popular front‑end frameworks, enabling seamless integration with existing applications while handling security, session management, and user data storage for you.
