Gerbil Scheme < https://cons.io > just saw its release v0.18, with many usability and documentation upgrades, and a bunch of new functionality in the standard library. A "meta-dialect of Scheme with post-modern features", Gerbil layers a Racket-like module system (the best in the world by far) on top of Gambit Scheme (compiler that produces the fastest code), with lots of libraries as "batteries included" for production-level client/server code.

this is such a cool scheme and has extremely talented people working in it. glad to see it progressing.

The Matrix/gitter is rather lively. The core team is pretty active there and good about answering questions

It's also fast! https://vyzo.github.io/lisp-benchmarks-game/
