An honest comparison. We use the others too — here is when each one wins.

In their own words
When to pick something else
Use Mermaid Live when…
You need a no-config sandbox to test a snippet. It's the canonical playground from the Mermaid project itself.
Use draw.io when…
Your diagram is mostly drag-and-drop, with Mermaid only as one block. The freeform canvas is the strength.
Use Lucid when…
You're in an enterprise that already pays for it and needs SOC 2 + admin SSO. The collaboration is great.
Use Excalidraw when…
You want hand-drawn whiteboarding for a meeting. It's the wrong tool for production docs.
