From my daily-use utilities, ripgrep and bat seem to have zero dependencies.

I believe ripgrep has only or mostly dependencies that the main author also controls. It's structured so that ripgrep depends on regex crates by the same author, for example.

Looking at Cargo.toml, ripgrep seems to have some dependencies and bat has a lot.
