What each one is

Buck2

Buck2 is a successor to the original Buck build system designed for fast, hermetic compilation of multi-language projects. It enforces strict dependency tracking to prevent common build errors and supports seamless interoperation between different programming languages like Python, OCaml, and Rust.
