Lucia Auth Has a Free Authentication Library: Session-Based Auth Without the Lock-In of Auth0 or Clerk

Auth0 costs $23/month for 1,000 users. Clerk costs $25/month after 10,000 MAUs. NextAuth hides session management behind magic. You're either paying a premium or fighting abstractions. What if authentication was just code you own? Sessions, cookies, password hashing — simple primitives you understand and control? That's Lucia. A TypeScript auth library that gives you building blocks, not a black box. What Lucia Is (and Isn't) Lucia is NOT a drop-in solution like Auth0. It's a library that handles: Session management (create, validate, invalidate sessions) Cookie management (secure session cookies) Session token generation (cryptographically secure) You provide: Database storage (any database — Lucia is adapter-based) Password hashing (Lucia recommends Argon2 or bcrypt) OAuth flows (if you want social login) UI (login forms, registration pages) Quick Start — Email + Password Auth import { Lucia } from " lucia " ; import { DrizzleSQLiteAdapter } from " @lucia-auth/adapter-drizzle " ; //
