SEPT 2026 audit

A comparison of Auth0 and Better Auth built from values read directly from each provider's own documentation, with the source recorded against every figure.

Reviewed by Palash BagchiUpdated 26 criteria comparedSources last checked

The short answer

Choose 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.

Editorial · Palash Bagchi · approved

Choose Better Auth if…

Teams that want the user table in their own database and no per-user bill at all — the framework is free, and the $20 plan buys tooling rather than access.

Editorial · Palash Bagchi · approved

Consider something else if…

  • 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.
  • Better Auth: You want a hosted service with an SLA rather than a library you run, since everything below the dashboard is your operational problem.

Documented by only one.

These criteria are published by one provider and not the other. An absence here means we have not found a source, not that the feature is missing — except where we say we read the other provider's own page on a given date and it does not state it. Those rows lean, and the provider can correct them with a link.

Credit card to startAuth0: No
Startup credit programAuth0: Auth0 for Startups: free access for venture-backed companies under $5M funding, under $1M ARR and under two years old.
Uptime SLABetter Auth: None by default. The terms say service level commitments live in a separate SLA or order form, and that absent one the service is provided on a commercially reasonable efforts basis.
Users includedAuth0: 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.
Price per SSO connectionBetter Auth: One SSO connection is included on the $20/month Pro plan, then $50 per month per additional connection; Directory Sync is metered the same way.
Support on entry paid planAuth0: Community support on Free; standard support on Essentials ($35/month), the entry paid plan.
SOC 2Auth0: SOC 1, SOC 2 and SOC 3 reports listed in Okta's trust centre (Auth0's parent), available on access request.
ISO 27001Auth0: ISO/IEC 27001:2022, with 27017:2015 and 27018:2019 alongside it; one combined report on access request.
HIPAAAuth0: HIPAA listed among the certifications in Okta's trust centre; no scope detail is published there.
PCI DSSAuth0: Auth0 offers PCI compliant environment deployment models; the Attestation of Compliance and/or SAQ-D is available on request through the Support Center.
Customer-managed keysAuth0: Bring Your Own Key imports a Customer Provided Root Key into a FIPS 140-2 L3 HSM, replacing Auth0's Environment Root Key for the tenant. Only users holding the Key Management Editor tenant role can use it.
Private networking / VPCAuth0: Private Cloud on AWS only, and outbound only: AWS PrivateLink reaches your own services from the deployment without exposing data to the internet. Set up by Auth0 after you file a request; Private Cloud on Azure uses Azure Private Link.
Dedicated infrastructureAuth0: Private Cloud on AWS is a dedicated, managed instance of the Auth0 platform with single tenancy, against the multi-tenant Public Cloud; Azure has the same option.

Questions this comparison answers.

Entry paid plan: Auth0 or Better Auth?

Auth0: $35/month for Essentials at 500 monthly active users; Professional is $240/month at the same volume. Both scale with the MAU slider.

Better Auth: $20/month for Pro on the managed infrastructure. The framework itself costs nothing — the plan buys a dashboard, audit logs and security detections around it.

Should I choose Auth0 or Better Auth?

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.

Pick Better Auth if Teams that want the user table in their own database and no per-user bill at all — the framework is free, and the $20 plan buys tooling rather than access.
