screenmgr

screenmgr is a tool for monitoring and managing a collection of computer screens. It communicates with devices on a local network via a number of protocols for monitoring uptime/reachability, viewing the screen, and remote control via a web interface.

My diverse collection of old computers was the motivation for this project. It originally was written in node.js and Perl, only supporting Mac OS 8/9/X for my Power Mac collection; but I later rewrote it in Go and added support for Windows and UNIX-like operating systems.
