Better Auth is presented as the most comprehensive authentication framework for TypeScript, designed to allow developers to "own their auth" rather than relying on external SaaS solutions.

Key Features:

• Framework Agnostic: Supports popular frameworks including React, Vue, Svelte, Astro, Solid, Next.js, Nuxt, Tanstack Start, and Hono.
• Email & Password Authentication: Provides built-in support for email and password authentication, along with session and account management features.
• Social Sign-on: Allows users to sign in using multiple OAuth providers such such as GitHub, Google, Discord, and Twitter.
• Two Factor Authentication: Enables securing user accounts with multi-factor authentication with minimal code.
• Multi Tenant Support: Offers features for organizations, members, teams, and invitations with access control.
• Plugin Ecosystem: Extensible with official and community-created plugins to enhance application experience.

Use Cases:

• Implementing comprehensive authentication in TypeScript applications.
• Integrating various authentication methods like email/password and social logins.
• Adding two-factor authentication for enhanced security.
• Managing multi-tenant applications with organizational structures and access control.
• Building full-stack applications with frameworks like Next.js and Nuxt, especially when combined with databases like Drizzle ORM.

Benefits:

• Comprehensive: Offers a wide range of authentication features.
• Type-safe: Provides full type safety, particularly noted when used with Drizzle ORM.
• Simple API: Described as having a "dead simple API" and good developer experience (DX).
