In my previous company, I used Kong, and in my current company, I'm using 3scale API Management, but I prefer Kong.

I previously used Oracle API Gateway.

I previously used Apiman and Keycloak community version.

Our clients need security patch management, that's why we are using 3Scale from Red Hat in order to get erratas (security fixes) integrated.

We checked Apigee, but it mainly failed for us. The way we wanted to write it required a cloud and our organization was not ready for pre-cloud solutions. It wasn't a good fit. It was possible to run it on prime, but that seemed like quite a big installation and ops to be running.

I have used similar solutions and I find that 3scale is more technical-driven. It uses great technologies and it is still easy for us to customize ourselves.

In terms of API management features, I think that it is less rich than the other major competitors. The way they manage the API is different, which is something that they can improve.
