What are FusionAuth and Better Auth?
FusionAuth is a complete authentication system that manages who can access your application and what they can do. You can install it on your own computer, your company servers, or use their cloud service. This flexibility makes it different from most authentication tools that force you to use only their cloud.
The platform supports all modern login methods - traditional passwords, passwordless access, social media logins, and biometric authentication like fingerprints. It follows industry standards like OAuth2, OpenID Connect, and SAML, meaning it works smoothly with other software.
There is a free version with all core features, and paid plans add extra security, support, and cloud hosting. The free version has no user limits, making it suitable for projects of any size.
Better Auth is a framework-agnostic authentication library that runs directly in your application. It handles user accounts, login sessions, and security features without relying on external services. You keep full control of your user data because everything runs on your own database and server.
The framework provides ready-to-use authentication methods including email and password login, social sign-in with platforms like GitHub and Google, passkeys for passwordless access, and magic link login. It also supports advanced features like two-factor authentication, organization management for team accounts, and role-based access control.
Unlike paid authentication services, Better Auth is completely free with no user limits or hidden costs. It uses modern security practices and actively maintained code to keep your applications safe.
