RustDesk (rustdesk.com) is open source, and similar to TeamViewer, and has paid plans, including a paid self hosted option.
It does need a server though. Either the centralized official one you can selfhost one.
Actually, (and I wasn't aware of this until you mentioned it, so thank you), it does support serverless connections:
So I think between cloud server, self hosted server and direct IP, OP should be covered.
Wow! I didn't know
VNC is dead. I'd try to talk them off that if it's a requirement.
VNC is dead.
How so?
There are a number of software packages in Debian that implement VNC. To grab one random example, the last commit to their git repo was last month.
VNC has long been abandoned by the engineering world. It's inefficient, it has no transport security, and the implementations are very subjective.
The last time I used a commercial VPS, I'm pretty sure it used VNC to provide console access.
The VNC software I linked to above appears to support TLS. If TLS isn't sufficient transport security, then most Internet-using software is going to be in trouble.
I'm not sure what you mean by subjective.
I haven't looked at the VNC protocol for a while, but I don't think that it imposes any terrible inefficiencies. A couple of decades back, I needed to implement something quick-and-dirty similar to VNC, and went with rendering window contents and handling dragging of windows locally, which I don't believe that VNC can do (or didn't then) but IIRC VNC has a tile cache, which, if intelligently used, should avoid most traffic. Dunno if it can deal well with efficiently rendering visual effects.

If OP is specifically wanting commercial support, they do mention two companies that provide services.

FreeRDP itself is a community driven open source project. However there are some people and companies that do offer all sorts of commercial support around FreeRDP:
- David Fort - Hardening Consulting - Contact
- Thincast Technologies GmbH - Contact
FreeRDP doesn't seem to be soliciting donations, though.
