Built a prototype GUI tool for testing Keycloak + Spring Boot auth — would you use it?

Hey, quick question for anyone who has worked with Keycloak and Spring Boot.

Have you ever spent hours debugging why your auth wasn't working? Wrong roles, token expiry issues, misconfigured endpoints. You just wanted something to tell you what's broken without writing any test code.

I built a small prototype of a GUI tool where you point it at your running Keycloak and Spring Boot app, hit run, and it tests your auth flows in 30 seconds. Login, role checks, token expiry, invalid credentials, all of it. No Testcontainers setup, no WireMock, no code.

Would you actually use something like this, and honestly would you pay for it or would it need to be free?
