TypeScript authentication framework that lives inside the application code and ships sessions, password reset, SSO, SAML, SCIM and MCP agent auth out of the box. Used by developers on Next.js, Nuxt, SvelteKit, Astro, Hono and 20+ frameworks, including teams at OpenAI, Databricks and Strapi. Auth lives in version-controlled, composable code rather than vendor dashboards and even supports auth for AI agents.
