Kinde vs Auth0
A comparison of Kinde and Auth0 built from values read directly from each provider's own documentation, with the source recorded against every figure.
The short answer
- Pick Kinde if
- Products that want a predictable flat fee and a large free user allowance that does not change when you start paying — 10,500 MAU on every tier is the opposite of Auth0's paid-plan cliff.
- Pick Auth0 if
- Projects that fit inside the free 25,000 monthly active users, which includes an enterprise connection, self-service SSO and SCIM at no cost.
3 sourced criteria separate them:
- Entry paid plan
- Kinde: $25/month for Pro. Plus is $75 and the top tier $250 — each including the same 10,500 MAU as the free plan.
- Auth0: $35/month for Essentials at 500 monthly active users; Professional is $240/month at the same volume. Both scale with the MAU slider.
- Pricing model
- Kinde: A flat monthly fee with the same MAU allowance at every level, plus a transaction fee when you bill your own customers through Kinde — 0.5% per transaction, discounted 0.1% on Plus and 0.2% above.
- Auth0: 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.
- Users included
- Kinde: 10,500 monthly active users on every tier including free. Paying more does not buy more users — Pro adds uncapped MAU billing, and the higher tiers add MAU discounts of 6% and 13%.
- Auth0: 25,000 monthly active users on the free plan — the largest free allowance here apart from WorkOS. Essentials and Professional start at 500 and are priced upward from there.

Consider something else if…
- Kinde: Enterprise SSO only becomes free at the $75 tier, and if you use Kinde's billing there is a 0.5% cut of your own transactions on top of the plan fee.
- Auth0: 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.
