Honestly, it's surprising how easy it is to port a Java CLI into a tiny web-app with @graalvm.org: parttimenerd.github.io/jhserr/ It is far superior to running the CLI on a webserver, as these leads to all sorts of security problems and also privacy concerns (especially with redaction tools).

Interesting comparison from the @quarkus.io maintainers shows that @graalvm.org native image remains by far the best option to deploy Quarkus applications for optimizing startup time, container image size, and memory consumption (RSS). Link in comments.
