Key takeaway: The case for Frontegg is the customer-facing admin portal, not the login. You get authentication plus self-service user management, roles and entitlements as ready-made surfaces, which is a lot of B2B product work deleted at once. If you only need auth, the bundle adds cost and complexity that Clerk plus WorkOS avoids.

What it is
Frontegg is the B2B-focused alternative to Auth0. Bundles auth + self-service admin portal + entitlements + audit. Aimed at SaaS companies that need enterprise features without building the admin surfaces themselves.
Best for
- B2B SaaS needing customer-facing admin portals out of the box
- Products where end-customer self-service is the differentiator
When not to pick it
Skip Frontegg if you only need auth, the bundled admin + entitlements increase complexity and cost. Clerk + WorkOS is often the cleaner combination.
My take
Niche between WorkOS and Auth0. Worth evaluating if the admin-portal layer matters as much as the auth.
Buying the admin surfaces, not just the login
Every B2B SaaS eventually builds the same set of screens: invite a teammate, manage roles, view an audit trail, configure SSO for your own company, see which features your plan includes. That work is unglamorous, it is never prioritised, and it is exactly what enterprise buyers poke at during evaluation. Frontegg ships those surfaces as embeddable components alongside the authentication itself, so your customers administer their own tenant without your support team acting as the middleman. For a small team selling to organisations that can be several engineer-months returned. The catch is that embedded, vendor-owned admin UI has to match your product visually and behaviourally, and the further your requirements drift from Frontegg's model the more you fight it. Evaluate by listing the admin screens you would otherwise build and honestly scoring how many Frontegg covers as it ships.
Sitting between WorkOS and Auth0
Frontegg occupies an awkward middle. WorkOS is narrower and cheaper if enterprise SSO and directory sync are the whole requirement. Auth0 is broader and more established if you need maximum federation coverage and a name procurement already recognises. Frontegg's argument is the bundle: auth, tenancy, entitlements and admin in one place rather than assembled from parts. That argument only works if you actually want all of it. Teams that adopt Frontegg for the auth alone tend to conclude they bought a heavier product than the brief needed, which is precisely what the directory entry warns about. The community is also smaller than either neighbour, so budget for reading official docs rather than finding a forum answer from someone with your exact problem. Choose it deliberately for the admin layer, or do not choose it.
Frequently asked questions
What does Frontegg do that Auth0 does not?
Ready-made, embeddable admin surfaces for your customers: team management, role assignment, tenant-level SSO configuration and entitlements, presented as components you drop into your product. Auth0 handles the identity side well but expects you to design and build the customer-facing administration around it yourself, which is often more work than the auth was.
Is Frontegg only for B2B?
Effectively yes. Its model is built around tenants, organisations and per-customer administration, which is B2B shape through and through. A pure consumer product would be paying for tenancy machinery it never uses, and Clerk or Supabase Auth would be a cheaper and better-fitting choice for that brief.
Frontegg or WorkOS plus Clerk?
Clerk plus WorkOS is usually cleaner and cheaper if you want great sign-in components and enterprise SSO, and you are willing to build your own admin screens. Frontegg wins when those admin screens are the work you most want to avoid, and you accept a single heavier vendor across the whole identity and tenancy layer.
