OCaml. Reason's just a syntax and toolchain layer on top of OCaml. The OCaml<->Reason interop should be seamless since we share the same abstract syntax tree. BuckleScript works fine in OCaml, naturally. Js_of_ocaml too.
Rust. Close cousin of ours. Not garbage collected, focused on speed & safety.
Elm. Another cousin of ours! Make clean, fun webapps.
PureScript. Inspired by Haskell, compiles to the web.
Fable. Based on F#, which is closely related to OCaml.
ClojureScript. Nothing in common with us on the surface, but prioritizes simplicity & great interop too.
Swift. Fruit-flavored OCaml!
Haxe. Compiles to basically anything.
