Product Introduction

1. Better Auth is a comprehensive authentication library designed specifically for TypeScript developers. It provides a robust framework for implementing secure authentication in web applications with minimal setup.
2. The core value of Better Auth lies in its simplicity, type safety, and extensive feature set that covers all modern authentication needs. It eliminates the complexity of rolling your own auth system while giving developers full control.

Main Features

1. Framework Agnostic: Better Auth supports popular frameworks including React, Vue, Svelte, Astro, Solid, Next.js, Nuxt, Tanstack Start, Hono, and more. This makes it versatile for different project requirements.
2. Email & Password Authentication: Built-in support for email and password authentication with comprehensive session and account management features. Includes secure password hashing and validation out of the box.
3. Social Sign-on: Supports multiple OAuth providers including GitHub, Google, Discord, and Twitter. Simplifies the process of implementing social login while maintaining security standards.
4. Two Factor Authentication: Provides easy-to-implement 2FA security with just a few lines of code. Enhances account security without complicating the developer experience.
5. Multi Tenant Support: Offers organization memberships, teams, and invitation systems with access control. Ideal for SaaS applications requiring complex permission structures.
6. Plugin Ecosystem: Extend functionality with official and community-created plugins. The modular architecture allows for custom authentication flows and integrations.

Problems Solved

1. Better Auth addresses the pain points of implementing secure authentication from scratch, which is time-consuming and error-prone. It provides a battle-tested solution that handles security concerns properly.
2. The target user group includes TypeScript developers building web applications who need reliable authentication without vendor lock-in. It's particularly valuable for full-stack developers and startups.
3. Typical usage scenarios include implementing login systems for web apps, adding social authentication, securing admin dashboards, and building multi-tenant SaaS applications with complex permission systems.

Unique Advantages

1. Unlike many authentication solutions, Better Auth offers full type safety and excellent developer experience while being framework agnostic. It combines the best aspects of libraries like Auth.js with improved DX.
2. The innovative auto-generation of database schemas (like for DrizzleORM) sets it apart, saving developers significant setup time while maintaining flexibility.
3. Key competitive advantages include its simplicity (can be implemented in minutes), comprehensive feature set, active community support, and the ability to "own your auth" without relying on third-party services.
