Excalidraw

Turn ideas into shareable hand-drawn diagrams quickly

EDITOR NOTE · Editorial advice, based on public sources

Recommended as a low-friction thinking whiteboard: sketch structure, discuss it, then move to Figma when precision matters.

Checked: 2026-10-12 · Official site material

Best for

Flowcharts, system sketches, wireframes, teaching, and collaboration that should start without a heavy setup.

Not for

Pixel-perfect UI, complex design systems, or long-lived team projects needing project management and granular asset permissions.

Key capabilities

Infinite canvas and hand-drawn expression

The official free plan includes the full editor, an infinite scene, and PNG/SVG/file export; its hand-drawn style keeps meeting sketches faster than formal design.[1][2]

Link collaboration and export

People can collaborate by link without each needing an account; Free suits one-off discussions, while Plus adds durable cloud-saved scenes and folders.[1][3]

AI and developer interfaces

The pricing page lists Mermaid-to-diagram, text-to-diagram, wireframe-to-code, and MCP; Free has a smaller AI allowance and Plus raises the daily quota.[1][4]

Pricing and free allowance

Free
Free forever; USD 0
Full editor, one infinite scene, unlimited collaborators, and PNG/SVG/file export; the source does not state a cloud-retention period.[1]
Plus
USD 6/user/month; annual price should be checked after switching billing
Adds unlimited scenes/folders, cloud save, permissions, comments, presentations, voice/screen sharing, and a higher AI allowance (100 requests/day shown on the page).[1]

Limitations to watch

Free storage boundary

Free is primarily browser-local E2EE with one scene; multiple cloud scenes and team management are the clear upgrade triggers.[1]

AI allowance limits iteration

The current comparison shows 10 versus 100 daily AI requests; after the allowance is used, switch to manual editing or your own key.[1]

Editorial workflow: how to try it

1

Sketch structure first

Use rectangles, arrows, and short labels to map one user flow without polishing visuals.

2

Share for feedback

Send a view or edit link and collect disagreements in one place.

3

Export or migrate

Use PNG/SVG for explanation; move to Figma for components, specs, and exact dimensions.

When is it worth paying?

Upgrade to Plus when local scene management, cloud saving, comments, or team permissions become bottlenecks; one-off meetings and teaching usually fit Free.
