I got tired of QR generators with ads, signups, and servers storing my data. So I built the simplest alternative: one HTML file, no backend, no tracking. Everything happens in your browser — WiFi passwords, contacts, URLs never leave your device. Supports 8 QR types. Download as PNG. Free forever. Open source.

Hey Product Hunt! 👋 I built 0qr.app because I kept running into the same problem: every QR generator I found either showed ads, required signup, or sent my data to a server. That last part bothered me the most — why does a tool need to know my WiFi password or contact info? So I made the simplest version I could imagine: a single HTML file, no backend, no server. Everything runs in your browser. Nothing leaves your device. It supports 8 QR types — URLs, WiFi, vCard, Email, SMS, WhatsApp, Phone, and plain text. Download as PNG, copy to clipboard, pick a color theme. Would love your feedback — especially if something doesn't work on your device or browser. Happy to answer any questions!
