I want tolike this. I hatethe state of infrastructure diagramming, but one of my primary complaints is that I dont like the inability to run the prettier ones locally.I don't want to trust enumeration of my system to yet another company.
That said, this is quite pretty.
Draw.io/ diagrams.net runs locally according to the documentation. E.g, you download the JavaScript app when visiting g the page and everything from there on is handled in the browser.
You can also install it in a rocker container.
