For those noting "why don't you just use Linux / k8s / ...", that feels close to the original complaints re: Dropbox on Hacker News[2]. I've run clusters hundreds of nodes in size myself but CapRover gives me the pleasure of not having to sweat the small details. You can get this from other platforms but usually there's a dollar cost tied to each option. When I'm experimenting I don't want to have a dollar cost attached.
Deploys are trivial. The default nginx setup is most of what I'd want to do. LetsEncrypt is a single button click. Monitoring is included by default. If I need to scale up, everything I'm pushing is Docker containers. If I want to experiment, there's great fun in looking at the included "One click apps / databases" and just playing around.
CapRover is just a lovely freeing experience that will do what you need :)
