Even if the data is passing through cloudflare cdn uses the cloudflare certificates my data is encrypted first using my own certificates from the Proxyserver

This is false, connect to your website, check the certificate, it will be Cloudlfare’s. I assume either you have not checked, or are a Business customer paying quite some money yearly to Cloudflare.

Cloudflare decrypts inbound traffic, then re-encrypts it before sending it to you, unless you pay a decent amount of money so that they serve your certificate.

Oracle gives free VPS, permanently free. Have a backup of these VPSes though, Oracle sometimes (haven’t experienced it myself, but some people here did) kills these VPSes.

You absolutely can mount different files from different servers simultaneously in vscode

It’s not in vscode then, it is on the filesystem if I understand correctly. Then even notepad can handle that.

sshfs causes weird permission issues for every server I use and cannot save files, so that’s not an option.

Managing docker-compose files over a few servers.

Notepad++ is fantastic, I can have multiple tabs with docker-compose files from different servers (via a ssh plugin), in a single window.

I was advised to move to VSCode or VSCodium. Neither can handle a single window with files from different servers, I need to switch workspace every time. Back to Notepad++.

No need to expose to the Internet. You can e.g. expose them to Home-Assistant/openHAB only, or VPN to your LAN then connect to them.

PfSense can do that
