This is exactly how I felt too. I was using portainer before, but the polish on Dokploy is insane.
Breaks when you use anything but bash as root user shell. Breaks if you have images in private registries with swarm. Breaks if you wanna restrict the API key access to just one project (the key can access all projects lol).
It's a great piece of software, I use it myself. But calling it polished in any way is a bit of a stretch.
I tried coolify couldn't get it running properly on the same VPS I got Dokploy to just work on the first try.
I tried SwiftWave and Coolify for that. They seem to support that if I understood you correctly.
I also love their template gallery of pre-existing projects, managed to setup auxiliary stuff like Plausible and Ghost which I wouldn't have done if it wasn't for the one-click install.
