Excalidraw

Excalidraw is a design tool for design work. In its own words: Excalidraw is a virtual collaborative whiteboard tool that lets you easily sketch diagrams that have a hand-drawn feel to them.

What the free plan gives you

Free whiteboard, open source core. Taken from Excalidraw's own pricing page, the free plan includes discord; github 130.6k; sign in; free whiteboard.

Because Excalidraw is open source, the ceiling is your own infrastructure rather than a billing page. Self-hosting costs nothing but your time, and a hosted plan is there if you would rather not run it.

When you would pay

You may never need to. The free tier is not a funnel step here, so the sensible move is to use it until something it genuinely cannot do forces the question.

We list Excalidraw because the free plan was checked against its own pricing page, not because a vendor asked. If it has changed, tell us and we will re-check it.
