This is very cool thanks. It would be awesome as a PWA so I can have it installed on my home screen/use it offline (edit: it looks like I misunderstood what the website meant by "runs on the browser" - I didn't it has a server dependency. Even so, it's easy to get Claude to generate a manifest and service worker to make it a PWA).
Also, minor UX feedback. Make the barcode type the first form field.
