A bit like the last question here: I'm looking into technologies and frameworks for creating web services that also provide a content management system. We've been using Drupal (php) for this at our office most of the time, but it feels like the framework is blocking us too much. After looking into Symfony CMF (also php), I wonder if there are any good JVM solutions for this? I used Spring Boot and Ktor but I wonder if you know a recommended solution for a CMS that can be coupled with these?

If your looking for a Java based cms you might want to take a look at https://www.onehippo.org it might be to much for your needs, also since the platform is quite old (last big rewrite more than 10 years ago) there is some lagacy.
