How can I allow all domains for Keycloak on my development machine?

We are a web application development agency. We create many web apps for our customers per year.

In the development environment, it’s getting hard to set up a separate Keycloak for each project we have.

Thus we thought of having a central Keycloak instance in our development environment, that is very generic. Like allowing all origins, all redirect URLs, having an admin user, having a super admin user, having a simple user, etc.

I created a Development realm and added a client named AdminPanel with https://* as the Root URL. I accepted that and created the client. But when I want to use it in my app, I see We are sorry… Invalid parameter: redirect_uri message.

So, is it possible to configure Keycloak to whitelist all domains and hosts?
