I'm a Network Engineer with a passion for diagrams. I developed CrossCanvas with an ethos of simplicity and usability. Combined with PingCanvas, it converts any diagram into a monitoring dashboard.
CrossCanvas - network diagram editor
A lightweight, locally hostable editor that runs in any browser with no build step and no network calls. Imports Visio, Gliffy, and draw.io diagrams plus common device-inventory formats, so you can diagram an existing environment fast instead of starting from a blank page. Public domain.
PingCanvas - live monitoring wall
Point it at a CrossCanvas board whose devices carry IP addresses and it becomes a status wall that recolors each device by reachability. A small PowerShell poller pings; a read-only kiosk shows the result on any screen.
