Frontegg

Overview

Frontegg is a customer identity platform built specifically for B2B SaaS. Where general CIAM tools treat organizations as an add-on, Frontegg makes the multi-tenant model, account hierarchies, and customer-facing admin experiences first-class, so SaaS teams can ship the identity their enterprise buyers expect without building it.

What it is good at

B2B depth. Tenants and sub-accounts, granular roles and permissions, and self-serve admin portals are core, and Frontegg leans into the commercial angle: gating enterprise SSO and SCIM behind plans so customers can upgrade themselves. Developer experience is strong, with embeddable components and good SDKs, and it added agent-authentication features as the agentic wave grew. For a SaaS company moving upmarket, it removes a lot of identity engineering.

Where it falls short

The B2B focus is also the limit: it is not aimed at high-volume B2C consumer identity, where per-user economics and social-first onboarding favor others. It is SaaS only, so self-hosting and controlled residency are out, and it competes in a crowded developer-CIAM field against WorkOS, Clerk, and Auth0. Governance and audit are light.

Pricing

Usage-based with a free tier, scaling by tenants and active users. Reasonable for SaaS startups; validate as your customer count grows.

Best for, and who should look elsewhere

Choose Frontegg when you sell B2B SaaS and want a rich multi-tenant identity and admin experience out of the box. For enterprise SSO/SCIM as a focused layer choose WorkOS; for React drop-in UX choose Clerk; for B2C scale choose Auth0 or Stytch. See Frontegg vs Auth0.

Bottom line

A strong, B2B-native CIAM that gives SaaS teams enterprise-grade multi-tenant identity without building it, less suited to consumer scale.
