Reminds me of wired elements (which uses Rough.js under the covers).

I've seen many hand drawn effect css libraries but what I like about this one is that each control has its own unique stroke. Pretty neat

Maybe I'm old fashioned, but usually when something says "hand drawn", I'd expect it to be hand drawn, not machine drawn

The comic sans of UI controls?

Where can I see a live demo that works on mobile?

Those feel very ink-blobby - like they were drawn by someone who can barely hold a pen stick-stopping across each line and then redoing parts of each line to correct mistakes. Looks elementary schooler.

I think I personally prefer Excalidraw look and feel - a couple of smooth and mostly straight lines per line, which looks more like intentional competence with a quick and imperfect tool.
