The other day I vibed a very stable codeserver (vscode in browser) instance with zellij browser mode (console in browser), syncthing (filesyncing), ssh, pi agent and wireguard. No exposed ports, every web frontend is password secured.

I don't want to make that public, it's my way of an isolated dev environment and it runs on my private raspberry behind my tv. Costs me nothing.

I hope you have a good success with your service.
