RealVNC Viewer: nine megabytes of remote desktop
The smallest app in this category and the highest rated — 4.8 across 15,227 reviews. Works with Windows, macOS and Linux alike.
Nine megabytes — twenty times smaller than Microsoft's client for the same core job, and the best rating here at 4.8.
What it does better
All three operating systems equally. VNC is not tied to Windows, so a Linux box at home is a first-class target. For anyone running a home server, that often makes this the only comfortable option.
It does one thing. No account management, no virtual desktop catalogue, no device enrolment.
The limits
RealVNC Connect on every machine you control, and a RealVNC account. The free tier caps how many devices you can register.
VNC is slower than RDP on a weak connection. It ships pixels; RDP ships instructions for drawing them. Over hotel wifi you feel the difference.
