Ask HN: Alternatives to Team Viewer?

I have several machines around the country that I need to remotely manage. Team Viewer has been unreliable and I'm looking to move our organization away from it.

Can anyone recommend a better remote management solution?

Guacamole?

Let me add to this that in addition to OP stating that it has been unreliable I think there are two other big reasons to move away:

1. TeamViewer is used a lot for Microsoft scams and AFAIK they don't care very much.

2. Dark patterns. TeamViewer upgrade their protocol all-the-time and once one part has updated the others have to as well, forcing the cost on everyone. (And the pricing is outrageous IMO. When you can get a full office suite for less than the subscription cost of the remote support solution then something odd is going on.)

It costs money, but there's always the BOMGAR box.
