Grails is on version 3.x but not many people upgraded from version 2.x or are starting new projects in it, and the Grails 2 plugin ecosystem is dead. I don't know of any other web framework which uses Apache Groovy for its scripting. Groovy is mainly used in industry to script Gradle and write glue code for Java. If you want static typing, best skip Groovy and use Java, Kotlin, or Scala which were statically typed from the ground up, instead of having it bolted on in version 2 as did Groovy.
