Ask HN: Diagram tools?

I'm trying to formalize some of our network and data flow diagrams. What tools are you guys using these days for building these types of diagrams? Vizio was my previous go-to but I'd like something that has some nicer defaults and is easier to work with.

I like Cloudcraft, but it's AWS-specific.

  • I used draw.io, it has AWS images and supports embedding the diagram markup within a PNG on export so you can upload the master to your corporate wiki/share it with colleagues

  • Archi https://www.archimatetool.com is very good if you are willing to follow Archimate.
