Mainframe
A wall of remote desktops
Mainframe turns a pile of remote machines into a single wall you can watch at a glance. Add your PCs, servers, and VPSes and they appear as live RDP viewports in a grid you can size from 2×2 all the way to 6×6. The wall is view-only so nothing gets touched by accident; expand any tile for full control, go true-fullscreen, or yank a single screen out into its own free-floating desktop window and place it wherever you like.
A This-PC panel shows your own machine's address, name, and username so you always know exactly what to connect to, and a toast pops the moment any connection drops. Connections are saved with passwords encrypted by Windows DPAPI and reconnect on launch. It runs from the system tray and updates itself silently. Free to use — claim your license key and download it straight from this page.
