Authaz vs Auth0

All the enterprise primitives. Without the add-on maze.

Auth0 was built for B2C login. Authaz was built for the way B2B SaaS actually models identity — organizations, customer-managed SSO, and per-tenant authorization, on every tier.

We don't think Auth0 is a bad product. We think it isn't built for B2B SaaS the way Authaz is. Here's what changes when you move to a platform where multi-tenant, SSO, and authorization aren't paid features.

Where we differ

What changes when auth is built for B2B SaaS.

Axis
Auth0
Authaz
Multi-tenant
Organizations as a paid add-on. Tenant model shaped around B2C apps.
Organizations and members as first-class primitives. Tenant-scoped tokens by default.
SAML SSO
Enterprise tier. Per-app rather than per-tenant.
Every paid tier, per-tenant, with test mode included.
Authorization
Bring your own. Or buy FGA as a separate product.
RBAC, ReBAC, and per-tenant policy in the same SDK.
Audit logs
Limited retention. Pricier exports.
Immutable, exportable to your SIEM or S3, retention by tier.
Pricing model
MAU + add-ons. Surprises at renewal.
MAU-based. Security on every tier. No paywalled SAML.
Vendor lock-in
Rules engine, custom hooks, bespoke flows.
Declarative policy you can read, version, and migrate.
Built for the pain Auth0 charges extra for

Stop paying for enterprise readiness as an add-on.

Organizations are first-class
Members, roles, customer-managed SSO — modeled correctly out of the box, not a separate SKU.
Authorization comes with auth
RBAC, ReBAC, and org-scoped policy ship in the same SDK as login. No extra contract.
Audit you can actually use
Immutable, filterable, exportable. Designed for your SOC 2 evidence pack, not just dashboards.
Predictable pricing
MAU-based pricing without enterprise add-ons. What you see is what you pay at renewal.
Migration

Bring users, tenants, and rules across without forcing a re-login.

Most teams move in one or two weeks. We help you map Auth0 organizations, rules, and roles to Authaz primitives, then run a dual-write window so nothing breaks for end users.

FAQ

Authaz vs Auth0, answered.

Is Authaz a good Auth0 alternative for B2B SaaS?

Yes. Authaz is built for B2B SaaS identity — organizations, members, and customer-managed SSO are first-class primitives, not paid add-ons. SAML SSO, per-tenant authorization, and audit logs are included on every paid tier, so enterprise readiness never arrives as a separate contract.

How much cheaper is Authaz than Auth0?

Authaz uses flat MAU-based pricing with security included on every tier. At scale it runs up to roughly 220x cheaper than Auth0, which layers organizations, SSO, and fine-grained authorization on top as paid add-ons that often surface at renewal.

Does Authaz include SAML SSO without an enterprise plan?

Yes. SAML SSO — both IdP- and SP-initiated, per tenant, with a test mode — is included on every paid Authaz plan starting at $25/month. With Auth0, SSO and the Organizations feature typically require enterprise pricing.

Can I migrate from Auth0 to Authaz?

Yes. Authaz provides a documented Auth0 migration path: organizations, rules, and roles map to Authaz primitives, and a dual-write window means end users aren't forced to re-login. Most teams complete the move in one to two weeks with migration support.

Is Authaz available yet?

Authaz is pre-launch. Early access is rolling out to waitlist teams now, with general availability staged through 2026. Join the waitlist to request an invite and lock in launch pricing — no credit card or contract required.
