How much does Auth0 actually cost?

Short answer

Auth0 is free up to 25,000 monthly active users with core features, paid B2C plans start around $35/month, B2B plans start higher, and enterprise pricing is quote-based. Cost scales with MAUs — community analyses commonly estimate ~$0.07/MAU effective cost at scale. As published July 2026 — verify with the vendor.

Why do Auth0 bills surprise teams at scale?

  • MAU math compounds: a consumer app's cost tracks active users, not revenue. Model 12–24 months of user growth against the MAU bands before committing.
  • Feature gates force tier jumps: the feature you need (MFA options, custom domains, longer log retention, organizations) often lives one tier up — you pay the whole tier, not the feature.
  • B2B connections are the real meter: for B2B SaaS, per-organization enterprise SSO connections drive cost more than raw MAUs — which is exactly where per-connection competitors position themselves.
  • M2M tokens are metered too: machine-to-machine authorization has its own limits and pricing.

Which auth provider should a Next.js B2B SaaS use instead?

It depends on your meter. If your cost driver is enterprise SSO connections, compare WorkOS. If it's consumer sign-ups with high churn, compare Clerk's retained-user billing and generous free allowance. If you need self-hosting or open source, compare Keycloak and FusionAuth. Our developer authentication comparison and Auth0 alternatives guide walk the decision tree with when-not-to-choose guidance for each.

Frequently asked questions

Is Auth0 really free, and up to how many users?

Auth0's published free plan covers up to 25,000 monthly active users (MAUs) with core login features, as published in July 2026. The free tier is generous for early products, but features like custom domains beyond the basics, richer MFA, and higher-tier support sit in paid plans. Verify current limits with Auth0.

How much does Auth0 cost at scale?

Paid B2C plans start around $35/month at low MAU counts and scale with MAUs; B2B plans (organizations, enterprise SSO connections) start meaningfully higher. Community cost analyses commonly estimate effective costs approaching ~$0.07/MAU at mid-to-high scale before enterprise negotiation — an estimate, not a published rate. Enterprise pricing is quote-based. As published/observed July 2026; verify with the vendor.

What forces teams off the Auth0 free tier?

Usually a feature gate, not the MAU cap: B2B needs (per-organization enterprise SSO connections), MFA and security policies in higher tiers, compliance/support requirements, or M2M token volume. Model your feature needs — not just MAUs — before assuming the free tier covers launch.

How does Auth0 pricing compare with Clerk, WorkOS, or Okta Workforce?

They meter differently: Auth0 bills on monthly active users (MAUs); Clerk bills on monthly retained/active users with a large free allowance; WorkOS prices per enterprise connection with a broad free tier for standard auth; Okta Workforce is per-employee per-product. Cross-vendor comparisons only work if you model your own user counts across each meter — as published July 2026, verify with each vendor.
