What is Better Auth?
For TypeScript developers, auth has long meant choosing between rolling your own (risky) or renting a closed service (lock-in). Better Auth offers a third way that's caught fire in the community — 'the most comprehensive authentication framework' for TypeScript, one that lives inside your own app rather than on someone else's servers.
Auth that lives in your codebase
Better Auth is a composable, plugin-based authentication framework that runs inside your application, giving you full control and no vendor lock-in. It provides built-in credential authentication with sessions, email verification and password reset out of the box — the essentials, implemented correctly so you don't reinvent them. Because it's a framework in your code rather than an external API, you own the whole flow and your users' data stays with you. It sits alongside self-hostable auth tools like SuperTokens, Logto and Ory.
35+ methods, from magic links to passkeys
Better Auth supports 35+ authentication methods, including social sign-on (Google, GitHub, Apple, Discord), passkeys, magic links and multi-factor authentication. That breadth means whatever login experience you want to offer, it's likely a plugin away rather than a custom build. The plugin architecture is key — you add exactly the capabilities you need and nothing you don't, keeping your auth lean and tailored.
Scales to enterprise
It's built to grow from a weekend project to enterprise scale. Multi-tenancy — teams, roles, invitations and access control — is built directly into the framework, and enterprise features include SSO, SAML 2.0, SCIM and directory sync, plus real-time security detection for bots, brute-force attempts and suspicious access. That means you won't outgrow it when you land your first big customer.
Framework-friendly
Better Auth works with Next.js, Nuxt, SvelteKit, Astro, Hono and 20+ more frameworks, so it fits the modern TypeScript ecosystem naturally rather than fighting it.
Who it's for
Better Auth suits developers building TypeScript applications who want flexible, self-hosted authentication without vendor lock-in — from solo hackers to enterprise teams.
Pricing
Better Auth is freemium: the open-source framework is free and self-hosted, with optional paid infrastructure services (a dashboard, audit logs, security detection and enterprise features) available on paid plans. You can build entirely on the free open-source core and add managed services only if you want them.
Bottom line: Better Auth is a comprehensive, plugin-based auth framework that lives in your TypeScript app — 35+ methods, multi-tenancy and enterprise SSO, fully self-hosted with no lock-in — which is exactly why it's become a developer favorite.
What is SchemaShield?
SchemaShield helps engineering and data teams review migration risk before deployment. Paste or replay a schema change to see affected downstream assets, severity, evidence, and concrete compatibility actions. The analysis is deterministic and reproducible, with a public demo, health endpoint, and open-source code.
