Guacamole Apache is pretty awesome

Meshcentral

I use rdp and tailscale. Best connection ever. Way better than vnc 3rd party connections or anydesk/teamviewer. If windows is the system at home, use rdp through tailscale or other vpn option

Set up a vpn on ur router and use rdp

I use mRemoteNG personally and professionally and always recommend it. Lets you store multiple types of connections, RDP, VNC, SSH, HTTP(S), etc. and you can open each window in tabs to have multiple open.

Tailscale and RDP.

I like RDC Man for several rdp sessions.

Just use RDP over Tailscale, done and free.
