Lucia is an auth library for your server. Unlike hosted auth services, you own the code, the sessions, and the database schema.

What You Get for Free

Session management — secure cookie-based sessions
Database agnostic — any SQL or NoSQL database
OAuth helpers — GitHub, Google, Discord, etc.
Password hashing — Argon2id
Full control — you own the code
Framework agnostic — Next.js, SvelteKit, Astro, Express

Session Management

import { Lucia } from 'lucia';
import { DrizzleSQLiteAdapter } from '@lucia-auth/adapter-drizzle';

const lucia = new Lucia(new DrizzleSQLiteAdapter(db, sessionTable, userTable));

// Create session
const session = await lucia.createSession(userId, {});
const cookie = lucia.createSessionCookie(session.id);

// Validate session
const { session, user } = await lucia.validateSession(sessionId);
