Dumb Diagrams turns a readable .dgm text file into an architecture diagram.
The engine validates the file, places resources, draws right-angle
connections, and checks the result. Studio, a local editor, lets you refine
the layout and saves your decisions in the same file.
New here? Make your first diagram. You need Node.js 24 or newer. There is no account and no hosted workspace.

AWS is the most mature provider. Azure, Google Cloud, and cloud-agnostic diagrams work but are still experimental. Dumb Diagrams is an architecture diagram tool, not a freeform whiteboard or a live cloud inventory.
