What Better Auth is
Better Auth is an authentication and authorisation framework for developers building TypeScript applications. The framework is free and open source, while its managed infrastructure is available on a free Starter plan, a $20-per-month Pro plan and custom Enterprise pricing.
It provides email and password authentication, user-account management and session handling, alongside social sign-on providers. Built-in features and plugins add two-factor authentication, passkeys, multi-tenancy and single sign-on. For self-hosted Better Auth, managed infrastructure provides a dashboard, audit logs and security features.

What the models said
“If you want full ownership, no vendor lock-in, and don't mind writing more code: go with Auth.js or Better-Auth.”
“Better Auth: best when you want full control, your own database/infra, and a more startup-friendly self-hosted model for a new greenfield app.”
“Reportedly the Auth.js maintainers themselves now recommend Better Auth for new projects.”
“Still very flexible, but recent evaluations suggest it’s best when migrating existing codebases, while new projects should consider Better Auth instead.”
