Pick Rapid if…

Rapid suits Go developers who want generated test cases for checking properties, especially for structured data or state machine tests. It may be less suited to those who need coverage-guided feedback or mutations.

Pick ScalaCheck if…

ScalaCheck is suited to developers testing Scala or Java code with randomized property checks. It fits projects using sbt or the listed testing integrations, and can also be run standalone.
