Check out Kasm. It lets you soon up on demand “Workspaces” that can be isolated browser sessions to full Linux desktops. All from within a web browser.

No, no, no!!!

• Public access to services like a website: Cloudflare Tunnel
• Restricted access to just a few users: Cloudflare Tunnel + Cloudflare Application
• Exclusive restricted access the infrastructure: Tailscale

Tailscale and RDP.

This is my policy: For publicly accessible services like a website, I use a cloudflare tunnel. For restricted access to just a few users, I use a cloudflare tunnel and a cloudflare application to manage access authentication. For my exclusive restricted access to the infrastructure, I used tailscale.

It really comes down to what you are trying to accomplish. I used it for a while also. It is very friendly and it provides many good features and apps to work with. Ultimately, I found it to be limiting, so I switched to Proxmox VE and just created several VMs and LXC Containers to use for various purposes including Docker.

PROXMOX: It would make a very nice Proxmox server that could host many VMs and LXC Containers. I have a similar configuration (though an i7) that hosts 2 Windows VMs, a Windows 7 VM, a Docker VM, and a second Docker VM running Kasm. Everything is accessible externally either public using Cloudflare Tunnels or restricted using Cloudflare Tunnels + Cloudflare Applications. I have a 300x300 Internet connection, and while it doesn’t get a ton of use, it’s always very peppy, even remotely.
