This linter, written in Clojure, has fast startup time (milliseconds). This makes it suited for hooking up with your editor for getting fast feedback. It's compiled with GraalVM to a native binary.

It has seen steadily growing adoption since its inception. A list of companies that are using the linter: https://github.com/borkdude/clj-kondo/issues/438
