Here are some key reasons why you may want to use Better Auth instead of other auth libraries and services. ### vs Other Auth Libraries [#vs-other-auth-libraries] * **Framework agnostic** - Works with any framework, not just specific ones * **Advanced features built-in** - 2FA, multi-tenancy, multi-session, rate limiting, and many more * **Plugin system** - Extend functionality without forking or complex workarounds * **Full control** - Customize auth flows exactly how you want * **Flexible deployment** - Run alongside your app or as a standalone self-hosted auth server ### vs Managed Auth Services [#vs-managed-auth-services] * **Keep your data** - Users stay in your database, not a third-party service * **No per-user costs** - Scale without worrying about auth billing * **Single source of truth** - All user data in one place * **Self-host anywhere** - Deploy on your own infrastructure with full control ### vs Rolling Your Own [#vs-rolling-your-own] * **Security handled** - Battle-tested auth flows and security practices * **Focus on your product** - Spend time on features that matter to your business * **Plugin extensibility** - Add custom features without starting from scratch * **Production ready** - Works embedded in your app or as a dedicated auth server
