What _IS_ Arcane? I fail to understand from their website https://getarcane.app/

Is it a deployment automation platform where it can run a project’s docker services, with rollback and all?

so, the project is pretty much vibe coded, including the docs. It makes a lot more sense if you play around with it. It's just a docker host management UI, I like using it. It has gitops built in and a nice container log view. It doesn't do rollbacks, it only seems to sync from git and run compose up.
