[keycloak-user] Maximum number of clients (applications) in a realm

How much clients you have in mind?

Theoretically there is no any limit. At least at database level. Fact is 
that we didn't try to test admin console UI with very big number of 
clients. Feel free to create JIRA if you're seeing issues.

Another approach is to design your deployment so the number of clients 
is not too big. For example when adding new "machine" you can reuse 
already created clients (not sure if it's the approach which works for 
you, just a possible hint...)
