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.


Sorry, not an answer to your exact question… Dockge might be the answer if you need a web UI to manage Docker containers.
If you need something more specific, like a button dashboard to run custom commands, perhaps you could build your own with Vite (Node.js). You will need to understand basic HTML, CSS and JavaScript.(EDIT: OliveTin makes more sense.)As for authentication, you could configure a basic authentication on your favourite reverse proxy (such as Nginx), or look for something more advanced such as OIDC/OAuth2 through Keycloak.
OliveTin is exactly what I wanted (tbh, was heard to read with your crammed together text, thanks as well @bonenode@piefed.social for helping me spot it! )
Keycloak, Pocket ID, Authentik, anything of the sort does sort great as well! Thanks for the recommendation for the follow-up step! :-)
Ah! Sorry for the textdump, and thanks for the feedback. I’ll keep it in mind in the future.
For a button dashboard as you put it I once got OliveTin recommended, haven’t yet set it up though.
This is exactly what I wanted. Thank you!!!
