Lucia

Pricing snapshot

Pricing

Lucia is MIT-licensed open-source authentication tooling, so there is no Lucia subscription fee. The real cost comes from your hosting, database, email or OAuth providers, SMS vendors, and whatever security review and maintenance work your auth stack requires.

• Lucia does not meter logins, MAUs, or API calls, so it should be budgeted like a custom auth implementation rather than like Auth0 or Clerk.
• Database session growth, email delivery, and third-party identity providers are the most common recurring cost layers around Lucia.
• Because Lucia is a library rather than a hosted control plane, teams also absorb more implementation and security responsibility themselves.
• This is often cheaper in software terms but more expensive in engineering time than buying hosted authentication.
