Comparison
AscendKit vs WorkOS AuthKit
AuthKit is WorkOS's authentication product, free to a million monthly active users, with WorkOS monetizing enterprise connections at $125 per SSO or SCIM connection. If you are selling into enterprises that demand directory sync, AuthKit is the stronger choice and this is an easy call. AscendKit aims at the opposite end: seed to growth SaaS teams whose next problem after sign-in is onboarding email, lifecycle journeys, and surveys — the layer AuthKit leaves to other vendors.

| Best fit | Self-serve SaaS needing lifecycle | Selling into enterprise buyers |
- Bundles email, lifecycle journeys, and surveys that WorkOS leaves to other vendors.
- One flat price for the whole SaaS app-services layer, not auth plus a pile of integrations.
- One user record across auth, email, journeys, and surveys, instead of four vendor copies kept in sync over webhooks.
- WorkOS is purpose-built for enterprise SSO and SCIM, which AscendKit does not offer today.
- If your immediate need is selling into large enterprises with directory sync, WorkOS is the stronger fit.
Choose the stack you can maintain
Start with auth if you want. Keep the rest ready before lifecycle messaging, surveys, and customer data fragmentation turn into integration debt.
Start freeIs AuthKit free auth really free?
For authentication, yes — genuinely free to one million monthly active users, with no asterisk worth arguing about. If auth cost is your question, AuthKit wins and this page should not talk you out of it.
WorkOS monetizes enterprise connections instead: roughly $125 per month per SSO or SCIM connection. That model is excellent if you are not selling to enterprises, and it becomes the dominant line item the moment you are — ten enterprise customers is $1,250 a month before anything else.
So the real question is not price but shape. AuthKit is free where AscendKit charges, and charges where AscendKit offers nothing at all, because AscendKit does not do enterprise SSO today.

Which should you choose?
Follow your buyer. If your next ten customers will ask for SAML and directory sync, choose WorkOS — that is precisely what it was built for, and AscendKit has no answer.
If your next ten customers are self-serve signups who need onboarding email, a nudge when they stall, and a way to tell you whether the product is working, the enterprise machinery is irrelevant and the layer above auth is where your time goes.
These are different products aimed at different stages, which is why free auth from one and paid auth from the other are not really competing. The overlap is narrower than the category label suggests.
