I’ve been working more with architecture diagrams and system design lately, and I’m curious what tools people are using right now.

For a long time I used draw.io — it’s simple and flexible, but collaboration can get tricky when multiple people are involved.

I also tried Lucidchart, which solves some of that, but it felt a bit heavy for my workflow.

Recently I’ve been experimenting with DiagramDeck, a browser-based collaborative diagramming tool. It feels like a nice middle ground — especially for creating architecture diagrams, flowcharts, and other diagrams with a team.

Still exploring options though.

What are you using for architecture diagrams and system design? Any tools you’d recommend?
