What it is

Lucia is a lightweight, framework-agnostic TypeScript authentication library. It provides session management, user authentication abstractions, and database adapters without dictating your stack. Designed for developers who want full control over their auth implementation without a managed service.

When it fits — and when it doesn’t

A good fit for

  • TypeScript developers who need fine-grained control over auth logic and session management without a third-party service

Look elsewhere if

  • Teams wanting managed auth-as-a-service with no configuration

Known weaknesses
