Well, a lovely management system, basically. One can run and edit Docker Compose configurations in the browser, see everything that’s running, manage environment variables and see the logs. I mean, having written all that, I’m wondering why I don’t run it on my Mac instead of Docker Desktop.

Generically, Portainer can manage multiple servers at once, each running their own Docker.

For home server usage, I just use it as a frontend to docker-compose files that gives me a pretty UI I can access from a web browser, instead of needing to SSH in to the home server.
