Canary - A QR safety scanner
Inspect & score QR codes before your phone executes them
QRs are convenient, but they hide their instructions. Your phone acts before you can intervene, and scammers are taking advantage of that. Canary unpacks and scores a QR code before it touches your device - revealing the real destination, assessing its veracity, removing trackers, and flagging scams. You get a safety score and all the detail behind the code, then you decide if you continue. Canary is free - no signup, no ads, no user tracking.

QRs are so much more than just an image to shoot with your camera. Behind each code is a set of instructions that your phone will blindly execute. Normally it's a safe URL—which is why we scan without thinking—but QRs are also used to join Wi-Fi networks, process payments, add calendar events, trigger SMS messages, and more.
I’ve never trusted QR codes, even at restaurants—I'd always ask for a paper menu. 20 years in the cybersecurity industry has taught me to be skeptical, and I wanted a tool that would show me exactly what’s hidden behind the code before executing it. When my wife, kids and their friends said it was something they wanted too, I turned it into a real product.
Canary is my first self-published app on iOS and Android. I've started companies, managed dev teams, and shipped products before, but Canary is my first solo project.
It’s completely free, requires no signup, and does no user tracking. I pay for all back end infrastructure and API costs out of pocket. I’d love to hear your feedback, edge cases, or feature ideas!
Thanks, Product Hunt community!
