Better Auth

Self-hosted TypeScript auth framework

FreeAuth & user managementbetter-auth.com

What it is

Framework-agnostic TypeScript authentication library that runs inside your own app and writes to your own database. Covers email/password, social OAuth, two-factor, organizations, passkeys and API keys through a plugin system. Vercel acquired the project in July 2026; it stays MIT-licensed, self-hosted and community-governed.

Why it earns a slot

No per-MAU bill ever and no vendor holding your user table — auth becomes just another dependency. The plugin system covers most of what you would otherwise pay Clerk or Auth0 for.

Know before you commit

You own the hard parts: session security, email deliverability, rate limiting and breach response are all yours. Vercel's July 2026 acquisition preserves MIT licensing, but roadmap direction now sits with a hosting vendor.
