QR codes are on every menu, poster, package and business card — yet most advice about them is either a sales pitch for a subscription or a ten-year-old blog post. QRocket exists to fix that. We publish practical, tested guidance: what actually makes a code scan reliably, how big to print it, which colors break it, how to track campaigns without invading anyone's privacy, and how to spot the scams.
We also build the tools to go with the advice — a QR generator, reader, checker and barcode maker — all free, all running in your browser, with no account and no expiring links. The articles never require the tools, and the tools never require the articles. Start wherever helps.
