Every SaaS product eventually encounters the same problems.
Early on, authentication is a checkbox:
- "Users can sign in"
- "Teams can invite people"
- "Admins can reset passwords"
Then enterprise leads show up. Next thing you know, you’re dealing with questions about SAML, SCIM, just-in-time provisioning, role-based access and security, all of which you would rather not turn into roadblocks for product development. This is the point at which most teams realise that the "good enough" auth stack they put together is now a burden.
I tried WorkOS AuthKit and Radar, looking through that lens:
Not "Can I ship login fast?” but “Can this get me from Series A to real enterprise contracts without rewrites?”
In this post, I explain my thoughts and why, as I find out just how powerful WorkOS is for implementing modern enterprise auth in applications.
This article is sponsored by WorkOS. All opinions are my own, based on hands-on evaluation and real-world SaaS decision-making.
The real problem WorkOS is solving (and it’s not login UI)
Most modern auth tools are optimised for developer satisfaction at day zero. WorkOS is optimised for company survival on day 900.
The core idea is simple:
Keep enterprise identity complexity behind a clean API, so it doesn’t leak into or complicate the rest of your product code.
Let's break this down to see what that looks like:
- AuthKit handles how users authenticate
- Radar handles who should be blocked before they become a problem
- Admin Portal handles who your support team doesn’t want to talk to at 2 am
Individually, these exist elsewhere and together, they form something closer to an enterprise onboarding system, not just auth.
AuthKit is opinionated where it matters, and flexible where it counts
AuthKit is essentially a pre-built, customisable authentication experience which has been created around WorkOS primitives and powered by Radix UI. In my testing, what stood out to me was the fact that:
- You are not trapped in the "startup aesthetic": It is possible to use a different theme and customise without fighting default settings
- It is agnostic: You can deploy everywhere, with server-rendered apps, Modern SPAs or Hybrid Stacks
- You can design for identity features that you don’t want to reimplement: MFA, magic links, RBAC, passwordless, JIT provisioning; it’s already a baked-in part of the model.
It's not competing to win a prize on originality; it’s trying to prevent future refactors, and yes, NextJS integration is excellent.
Radar is security that doesn’t wait for abuse to happen
Many teams see fraud and bot protection as a generic add-on, but Radar turns them on their heads. Unlike bolted-on reCAPTCHA or retrofitted rate limits, Radar integrates into the authentication layer to:
- Detect automated abuse
- Block credential stuffing
- Reduce fake account creation
- Defend enterprise login flows before they can be exploited
What I liked here is the placement. Radar doesn’t live in "security tooling land." It lives where identity decisions already happen. And in my opinion, that’s the right architectural choice.
The Admin Portal quietly does the most valuable work
This is the part that most devs don’t take into account, until they’ve been burned. The Admin Portal provides customer IT teams with the ability to:
- Configure SSO
- Manage directory connections
- Onboard customer without engineering assistance
This directly reduces:
- Support tickets
- Custom onboarding calls
- "Can you hop on Zoom with our IT team?" requests
If you’ve ever been the engineer brought into enterprise onboarding calls, you instantly get the value here.
Where WorkOS fits, and where it doesn’t?
This is the most important section, because it gives us a grasp on how well WorkOS can be integrated into your own workflow.
WorkOS works well if:
- You are building a B2B SaaS with enterprise goals
- SSO, SCIM, and compliance are already being asked on sales calls
- You want identity to be infrastructure, not a product-surface
- You are thinking in terms of long-term stability and not short-term convenience
WorkOS is less suitable if:
- You’re working on a consumer app or side project
- You desperately need deep auth customisation for UX tweaking
- You don’t want to pay for enterprise-grade features in the future
- You depend heavily on a non-NextJS stack today (support is getting better, but you get the idea)
It is not a one-size-fits-all tool, and that’s perfectly fine.
How does WorkOS compare to other competitors?
This isn’t a feature-by-feature breakdown. It is what those tools feel like when you move beyond Minimum Viable Product (MVP) and start interacting with real customers, real security concerns, and actually scaling.
Auth0: Battle-tested and powerful, with solid enterprise features; however, also more heavyweight, complex and expensive as you grow. You’re paying for flexibility, whether you want it or not.
Clerk: Fantastic developer experience and lightning fast to ship early. Good choice for startups, not a priority for enterprise onboarding (SSO/SCIM/IT-led setup).
Kinde: Clerk in spirit, clean DX, quick wins, good defaults. The perfect fit when speed is better than long-term enterprise solutions.
Stytch: Pretty powerful and modular, with nice APIs. It can be like Lego blocks, where you assemble it yourself, as opposed to a more thorough enterprise onboarding system.
Descope: Robust no-code / low-code auth workflows and flexibility. It is powerful, but also opinionated, in a way that might not be great for teams who prefer Auth to stay out of the way.
Ory: Open-source, and a platform worth checking out, as it is very flexible. Great, if you actually want full control and aren’t afraid of having to maintain complexity in infrastructure and long-term support.
Amazon Cognito: Plenty of scalability and built into AWS. Very developer-oriented with lots of complex configurations and setups.
Firebase: Good for shipping a product quickly. Enterprise identity (SSO, directories, IT-managed onboarding) can be tricky, though.
Supabase Auth: Amazing DX, and it has an open-source feel to it. Similar to Firebase, awesome at the startup level, but enterprise requirements would drive you to a custom solution.
Frontegg: A decent amount of enterprise focus, many things are already built in. Might be heavy and product-defining (not infrastructure you quietly rely on).
Better Auth: More approachable and developer-centric. Perfect for people who want to have a framework-agnostic solution and don’t yet need enterprise-grade identity workflows.
Where WorkOS comes in
It might not be the absolute quickest way to have a demo login, but it’s one of the cleanest paths from "startup auth" to enterprise-ready identity without rewriting half your stack down the road.
WorkOS covers a lot of bases and does it very well, which makes it a good all-around provider.
The trade-offs you should actually think about
No tool is free of compromise.
What really surprised (me in a good way) is how well AuthKit and Radar seem to work together. They don’t appear like a set of loosely linked features, but more like parts of one system, engineered to address real enterprise identity issues. Much of the detailed control you would normally have to deal with around SSO, provisioning, and abuse protection is still there, but it’s purposefully buried behind default settings and a clean UI that never makes you feel like you’re staring into a black box.
What didn’t work quite as well is largely a matter of scope and timing. Stack support beyond NextJS is still a little bit constrained, something that will be important to teams running less popular configurations. The free tier is great for exploration, but doesn’t really show off what WorkOS can do; most of the value only becomes clear when you’re really trying to think through enterprise use cases.
Finally, integrating with WorkOS is as much a mental shift as a technical one: you're basically choosing to continuously look at your product's future from an enterprise ready lens. If you’re one of those hoping to stay small forever, then this will likely all seem like overkill. For people who do hope to grow, it is much more like insurance.
Conclusion
WorkOS AuthKit and Radar will not instantly make your product feel magical. They will make your sales pipeline less fragile, your security stronger, and your engineering roadmap quieter.
If you already have enterprise goals, even if they’re barely there, it’s worth assessing now instead of putting them off and giving WorkOS a try.
