Authentication scaffolding auto-detects your framework and provisions a complete Better Auth setup, including database adapters, route handlers, and OAuth providers for TypeScript applications.

You can retrofit authentication into existing Next.js or Express projects by auto-detecting existing patterns and generating tailored OAuth providers and route handlers for your current stack.

Better Auth scaffolding supports SvelteKit and Astro by guiding framework detection and generating adapter configurations, route handlers, and UI pages for these modern stacks.

The fastest way to scaffold sign-in and sign-up UI pages is using the Better Auth CLI to generate framework-specific configuration and ready-for-integration frontend pages across your JavaScript layers.

Framework detection scans your project to identify your modern stack, existing auth patterns, and database adapters, which dictates the generated route handlers and OAuth configuration.

During Better Auth setup, the scaffolding generates database adapter configurations tailored to your detected environment, ensuring a consistent security baseline across frontend and backend layers.
