It sounds like the OP may be looking for something that can be provisioned for multiple users, which Caprover doesn’t really have facility for. That said, the one-click-app templates are very easy to read/edit/update/create, if you can create a Docker Compose spec, you can create a template for Caprover.
I like that it’s really just a frontend for Docker, all of its functions are built around standard API calls to Docker. It means that I can install Portainer as a one-click-app, and use it to manage all of my other apps, without sacrificing any features. I can also spin up Docker containers outside of Caprover, and as long as I don’t run into port conflicts, it functions exactly as it should.
Caprover is just a one-man-show, so development may not be as responsive or rapid as some may wish, but the maintainer is very active, and he responds to pull requests promptly. One Click App templates are largely community maintained, but since they’re so easy to deal with, it’s trivial to work around most common issues, like updating versions or exposing new environment variables, and once again, the maintainer is very good about merging pull requests for app templates.
