Replacement for Rundeck?

Somebody I’m helping has an ancient, and i mean ancient (like 3 major versions before latest or so) install of Rundeck doing stuff for them. Might help them upgrade it to the latest (more like reinstall and configure from scratch, it was built years ago with assumptions no longer true), but before i commit I’d like to know if there’s decent replacements/alternatives for it these days.

In case you don’t know Rundeck, it allows you to set it up so that a number of users, with various privilege levels, are allowed to execute scripts on remote machines, with whatever privileges the given script needs, giving them parameters from an allowed set you configure. That’s all, no more, no less.

Sounds like something that should be common, but when you look for alternatives it gives you everything that’s ever been touched by the word DevOps, from Ansible and every “configuration engine” software ever made, to automation libraries and the like. I just want something that does this and no more, let people run scripts while preventing them to break stuff. If it’s something commandline friendly (Rundeck wasn’t as far as i can see) much better, and doubly so if it’s user friendly (have tried AWX and feels like it wants to be able to run the whole of Google from a browser window, dislike it in general, far too convoluted, and not user friendly at all for the not very techie office workers that use Rundeck today).
