For example, if I want a website where users can I signin to choose options such as changing or restarting a Docker container. Or various other systems level options available from a web interface.
I’m looking for something in the cloud but also something self hosted at home.


This sounds exactly like what Cockpit was made to do…
100%, Cockpit is what you’re looking for OP.
Too many features. I should have mentioned that I want it very limited. For example, to give to clients to restart game servers.
Edit: Cockpit is great! But to give remote access to full user-level shell access is not something I want. It might have access to other features I would want to avoid like installing software. Instead I want strictly it to commands like,
Just host a webpage with 7 buttons triggering off your shell scripts.
You’re better off telling us the problem you’re trying to solve than come to us with a solution to something we have no idea about.
If you describe the problem first, we might have a better idea than a web shell, which in all honesty is a bad idea.
This. Sounds like a classic example of the XY Problem
You don’t have to use all the features. Restarting a service is a pretty broad feature. If it’s too broad, You will likely have to code something yourself.
What does that even mean? Are you looking for a bespoke system that does exactly what you want and nothing else?
Pterodactyl or Pelican if what you might want if you are looking to give tenants access to game servers on your own infrastructure.
