Better Auth is a framework‑agnostic authentication and authorization library for TypeScript. It provides a rich set of built‑in features and a plugin system for extending capabilities such as 2FA, SSO, and payment integration.

Use cases

• Add email/password login with email verification and password reset to a Next.js app
• Integrate social sign‑on (Google, GitHub, Apple) into a SvelteKit project
• Implement multi‑tenant user and role management for a SaaS platform
• Enable passkey and WebAuthn authentication for a mobile‑first web app
• Add API key and JWT authentication for a serverless backend
• Set up SSO with SAML 2.0 and SCIM for an enterprise dashboard

When to choose

• You need a TypeScript‑first auth solution that works across many frameworks (Next.js, Nuxt, Astro, etc.)
• You want a single library that provides both authentication and authorization out of the box
• You prefer a plugin‑based architecture to add features like 2FA, multi‑session, or payment integration only when needed
• You require built‑in support for databases (SQLite, PostgreSQL, MySQL) and stateless mode

When to avoid

• Your project is not using TypeScript or runs on a language/platform without Node.js support
• You need a lightweight, single‑purpose auth client without the extensive plugin ecosystem
• You prefer a fully managed SaaS authentication service with no self‑hosting responsibilities
