Hey, I had this idea a while ago
What if creating C4 software diagrams felt as easy as using a visual editor, while still generating Mermaid or Structurizr DSL?
The early public beta is now live.
Feedback is welcome ;)

Still relying on confusing architecture diagrams? 🏗️
Attend @simonbrown hands-on workshop to learn why most diagrams fail, how to fix them, and how the C4 model can help you create clearer views of your software systems.

From Reddit: "I wanted my agent to draw architecture diagrams for me. Mermaid and PlantUML both had me arguing with a layout engine about where a box goes, and with C4 I spent more time on modeling questions (is this thing a container or a component) than on the system I was trying to describe."
1. I also dislike automatic layout, which is why Structurizr was designed with manual layout as the default approach.
2. Creating a common language is exactly the value that C4 brings to teams. Skip this step at your peril!

A final reminder that the Structurizr cloud service will be shutdown at the end of September - please export your workspaces before then if you would like to retain them.
Migrating to the new Structurizr local (Lite equivalent ... docs.structurizr.com/local) or server (on-premises installation equivalent ... docs.structurizr.com/server) tooling is the recommended migration path, but there are a number of other community tools available (docs.structurizr.com/communi…) that can render Structurizr workspaces.

What is everyone using to automatically generate C4 diagrams from your architecture components? Manually curating architecture diagrams is not it

In the pursuit of agility, have teams abandoned software design altogether? 🏗️
In his #dev2next keynote, @simonbrown explores why architectural thinking and upfront design still matter, helping teams avoid costly rework and move faster.

@simonbrown and his C4 Model:
*Draw context and containers, mostly leave the rest
*The deeper levels go stale with every commit
*What matters is getting everyone to agree what the words mean

Your architecture diagrams have unlabeled arrows, mystery boxes & 12 different shades of blue. Nobody knows what any of it means.
@simonbrown wrote the book that helps & Susanne Kaiser asked him everything you need to know about it.
