About Better Auth

Better Auth is an open-source authentication and authorization library for TypeScript, distributed under the MIT license. Instead of sending users to a hosted identity service, it runs inside your own backend and stores users, sessions and accounts in your own database through adapters for Drizzle, Prisma, Kysely, MongoDB and plain SQL drivers. It is framework-agnostic, with integrations for Next.js, Nuxt, SvelteKit, Astro, Hono, Express and others, and typed clients for React, Vue, Svelte, Solid and vanilla JavaScript.

The core covers email and password, social OAuth providers and session management; a plugin system adds two-factor authentication, passkeys, magic links, email OTP, username login, organizations with teams and roles, admin tools, multi-session, API keys, JWT, an OIDC provider and more. A CLI generates the schema and migrations each plugin needs. The library is free with no per-user pricing; an optional managed service (free Starter, $20/month Pro) adds a dashboard.

Better Auth suits TypeScript teams that want control over user data and login flows without writing auth from scratch. The trade-off is responsibility: you handle hosting, security updates and email delivery, and the core ships no prebuilt UI components. Clerk and Auth0 provide hosted UI, dashboards and enterprise SSO for a per-user fee; Supabase Auth is convenient if you already use Supabase; Auth.js (NextAuth) is the older open-source option with fewer built-in features.

The project grew quickly in 2024 and 2025 as Lucia was deprecated.
