entr is written in C, watchexec is written in Rust. There's another one that I've used that is written in go: https://github.com/cespare/reflex I am inclined to use watchexec next time I need one, because like go, I can read it more easily than c, but also because I looked at the web page and GitHub repo and it seems worth trying.
