Beyond the checklist

Pick the platform that fits how you build

Pricing

A million users before the invoice gets weird

Authdog

The full platform includes one million MAUs free. Team starts at $19 per month for three seats, with enterprise SSO, provisioning, audit logs, and authorization included.

Auth0

B2B Essentials starts at $150 per month for 500 MAUs. It includes three enterprise connections; each additional connection costs $100 per month, up to 30 total.

B2B

Multi-tenant identity without stitching products together

Authdog

Organizations, tenant-aware sessions, SAML and OIDC SSO, SCIM and HRIS provisioning, audit logs, vanity custom domains, and customer branding share one data model and console.

Auth0

Organizations, enterprise connections, SCIM, self-service SSO, and organization-scoped administration are available, with entitlements varying by plan and add-on.

Authorization

Authentication and fine-grained access in one platform

Authdog

Start with roles, add attribute-based policies, then model fine-grained relationships without replacing your identity layer or operating a separate authorization service.

Auth0

Core Auth0 plans provide role-based access control. Teams needing fine-grained authorization can add Auth0 FGA as a separately metered product.

Developer experience

One integration. Social today, SAML when someone asks.

Authdog

Hosted identity pages, framework SDKs, APIs, webhooks, MCP, and console workflows cover authentication, user management, SSO, provisioning, and authorization.

Auth0

A mature SDK ecosystem and Universal Login cover broad authentication use cases. Advanced B2B requirements can span plan entitlements, add-ons, and separate products.

Authentication

Passkeys and MFA on the same hosted login

Authdog

Hosted WebAuthn passkeys plus TOTP, SMS, and push MFA, with SAML and OIDC SSO on the same identity host.

Auth0

Universal Login covers passkeys, MFA, and enterprise connections. Factor mix and entitlements vary by plan.

Operations

Custom domains, agents, and SIEM without a second stack

Authdog

Vanity custom domains, project MCP with agent tooling, and SIEM notification channels (Sysdig, Splunk, Sumo Logic, Microsoft Sentinel) sit next to Lidar Signals.

Auth0

Custom domains and log streaming are available. Agent and SIEM packaging varies by product and plan.

Deployment

Choose managed infrastructure or tighter control

Authdog

Use Authdog's managed edge platform. Enterprise customers can also choose on-premises deployment, a 99.99% SLA, and dedicated support.

Auth0

Use Auth0's public cloud, or discuss private-cloud deployment and custom service levels through an Enterprise agreement.
