Free tier

Flowcharts, wireframes, mind maps and docs on one fast canvas.
Four tools sharing a canvas and a keyboard-first feel: flowcharts that route their own arrows, low-fidelity wireframes with a real component library, mind maps and sticky-note boards. Being able to drop a wireframe next to the flow that leads to it is the reason product teams pick it over four separate tools. The free plan is where it bites — solo boards are fine, but anything you share with a teammate counts against a small quota.
Questions
A genuinely usable free tier with paid plans for volume or team features. The free plan caps shared boards — the moment you invite someone, the board counts against a small allowance.
Yes. Whimsical sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
