# Auth0

Canonical: https://inetgeek.com/auth/auth0/

Okta's developer identity platform, priced by monthly active users with sharply lower allowances on paid tiers than on free.

## Who it suits

Projects that fit inside the free 25,000 monthly active users, which includes an enterprise connection, self-service SSO and SCIM at no cost.

Consider something else if Leaving the free plan is a cliff rather than a step: paid tiers begin at 500 MAU, and a footnote says enterprise connections, SSO and SCIM need a B2B upgrade to keep.

## What the documentation says

### Pricing

- Free tier: Yes ([source](https://auth0.com/pricing), read 2026-09-06)
- Entry paid plan: $35/month for Essentials at 500 monthly active users; Professional is $240/month at the same volume. Both scale with the MAU slider. ([source](https://auth0.com/pricing), read 2026-09-06)
- Pricing model: Per monthly active user, chosen on a slider, with a discontinuity that is easy to miss: the free plan covers 25,000 MAU and includes an enterprise connection, SSO and SCIM, while the paid tiers start at 500 MAU and a footnote says keeping those three features requires upgrading to B2B.
