Pro
FutureNothing to buy yet, and no waiting list to join. If a paid tier ever arrives, it would likely be optional extras rather than a gate on what already works:
- Premium template packs
- Advanced export styles
- Commercial template collections
This describes a possibility, not a plan with a date. Nothing on this page collects payment details.
Why free?
Most diagramming tools charge because they store your files, run rendering servers and maintain accounts. DiagramDock does none of that: the editor is a static site and your browser does the work. There is no per-user cost to recover.
The trade-off
Worth understanding before you rely on it: no sync between devices, no collaboration, and clearing your browser data removes your diagrams. Export anything you would miss.
