The palette
Types you invent yourself
6 to start with, and none of them sacred. Name your own, give it a colour, drag it where it belongs — and the palette belongs to that board alone, not to the app.
The workspace for software architecture
Your software architecture, in one place
A box for every moving part, a line between them, and links that work out their own way around.
No account needed. Boards stay in this browser until you want them anywhere else.

The links
Lines that route themselves
You say what connects to what. Where the line goes, and what it steps around on the way, is not your problem.
Boards
One for every system in your head
Name them, switch between them, rename or delete them — most recently touched at the top. Each keeps its own diagram and its own palette, so none of them has to agree with the others.
Sharing & export
Send the diagram, not a screenshot
A link anyone can open, read only, switched off whenever you like. Or a file — and the file is drawn from the board, not scraped off the screen.
Everything else in the box
It saves itself
Half a second after you stop.

A board is stamped, not dropped.
Sharing is a decision
Private until you say so. Revocable after.

They get the picture, never the editor.
