As far as I can tell, https://excalidraw.com/ https://excalidraw.com/ is already possible to use offline, since it seems to be a PWA. Just a friendly reminder that "web !== requiring internet 24/7 internet connectivity", many client-side applications works even if you go offline, granted you have loaded the page at least once before. Try loading the page, disconnecting your internet and then doing a hard-refresh/reload your browser.
