Hey HN -

Qraft is something I made for fun after having a conversation with a co-worker about how it would be cool to embed long-form messages as QR codes in GIF format. There's a generator for creating the GIF and a scanner for reading them back. A sharable HTML page is created for each message with decoding instructions. A direct link to the image is also provided for embedding.

Is there a way I can try this without giving a random closed-source Web app access to my camera?

Not at the moment but the scanning feature is client-side only and does not rely on any external services. It uses jsQR[0] to handle parsing directly in the browser. One way to use it and be sure would be to load the page and disable the site's network connection using developer tools before giving camera access. Once done, allow camera permission, perform the scan then kill the page.
