FrontEgg

Frontegg is a B2B user-management platform: embedded auth, tenant/org modeling, admin portals, roles, audit logs, and product-facing identity UX; not just OIDC plumbing. We rate it assess alongside Auth0 when building multi-tenant Software as a Service and you want opinionated B2B flows without operating Keycloak-class infrastructure yourself.

Blurb

Frontegg is the user management platform for modern SaaS: authentication, authorization, and everything in between.

Summary

Vs Auth0: Auth0 is the general-purpose embedded IdP; Frontegg optimizes for B2B product surfaces (customer admins, invitations, tenant settings, embeddable components). Pick Frontegg when “user management as a product feature” dominates; pick Auth0 when you mainly need standards-based login and will build tenant UX yourself.

When to assess: B2B SaaS with per-customer admins, self-service onboarding, and compliance-friendly audit trails; teams that want hosted UI/SDK rather than custom screens on raw OIDC APIs.

When to skip: simple internal apps, single-tenant tools, or shops already standardized on workforce IdP + minimal app auth; strict build-it-all-in-house policies.

Ops: same criticality as any IdP, MFA for vendor admin, least-privilege API keys, DevSecOps review of webhooks and embed config, map vendor roles to app RBAC.
