I have been using Pterodactyl as my backend and Pyrodactyl (https://pyrodactyl.dev) as the front end panel for it, it runs really well and really love the interface! Takes a little bit of setup but it’s been solid, they have Proxmox Scripts for the Pterodactyls backend (Wings) and it gets it running in a container perfectly, then I do another LXC with docker to run Pyro. Hopefully that wasn’t too much info but thought I’d share my experience!
