Excalidraw Has a Free Whiteboard — Diagram Architecture Without Leaving Your Browser

Every Architecture Discussion Needs a Diagram

You are in a meeting explaining how the new microservice connects to the existing system. Words fail. You need a diagram.

Lucidchart wants $10/month. Draw.io is functional but ugly. Miro is great but overkill for a quick sketch.
