EDITOR'S TAKE

Note: Lucia announced deprecation in 2024 — the maintainer is sunsetting it in favor of writing your own. Still useful as a learning reference for session-based auth patterns in TypeScript. Better Auth picks up where Lucia left off.

Skip if

You are picking auth for a new production app — use Better Auth or Auth.js instead.
