Excaliwow runs on your own machine — the client starts it, so there is no endpoint to ping. 50 installs a week from npm. Last commit 6 Aug 2026.
Create, read, render, organize, and safely edit persistent Excalidraw diagrams with AI agents.
Nothing serious here today
Today is the operative word: we check Excaliwow every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
