At long last, systemd-client: merry meet! Next step is such a TUI for non-Linux such as macOS, FreeBSD, Windows. For macOS I use LaunchControl.app but it isn't a TUI.

Just one thing: I had to do

  $ uv tool install git+https://github.com/isd-project/isd

instead of

  $ uv tool install https://github.com/isd-project/isd/isd@latest

and uvx wouldn't work at all, version: uv 0.5.21. That said, uv is way more quick than pip(x) so I just switched.
