01, Cost

Priced on success.

Auth0 prices its plans on monthly active users, with enterprise terms by quote. For a digital bank or insurer, monthly active users are exactly the number you are trying to grow, so the identity bill rises with every channel that works.

Midships Keycloak is a subscription on the deployment. Model the difference with your own figures in the Keycloak savings calculator.

02, Control

SaaS by design.

Auth0 runs as SaaS, either multi-tenant or as a dedicated private cloud on AWS or Azure. Your own data centre is not among its listed deployment options. For many digital businesses that is the point. For a bank that must keep customer identity inside its own tenancy and change control, it is a constraint.

Midships Keycloak runs on premises or in your own cloud tenancy, under your controls.

03, Getting to production

Fast to start is not the same as ready for a bank.

Auth0 is quick to integrate for a first application. Enterprise programmes still need journey design, federation, migration of existing customers, performance testing and operational ownership. Midships Keycloak includes the production platform, and builds journeys with Caravel to the same standard each time.

Verdict

Which is right for you?

Choose Auth0 if

you are a digital-first business that wants SaaS, has modest active user numbers, and does not need identity in your own environment.

Choose Midships Keycloak if

you are a regulated enterprise with large or growing customer numbers that needs identity in your own environment and predictable cost.
