Built in Go, 6 MB single binary, that's nice. The saved commands per venv thing is something I haven't seen in other venv managers. I keep a shell alias per project that activates the venv and runs the dev server but having that saved per-venv in the tool itself is better.

Thanks. Aliases live in your shell config, but the commands you actually run are tied to the venv. Felt natural to attach them there.
