Qravio is a dynamic QR code generator with real-time scan analytics. Unlike most "free" QR tools that watermark your codes or only make static ones, Qravio's free tier creates genuinely no-watermark dynamic QR codes you can edit after printing — change where a code points without reprinting it. Create trackable QR codes for websites, PDFs, vCards, business profiles, events, WiFi, social links, coupons and more (20+ types), each with a branded landing page, and track scans in real time by time, location and device. Paid plans add custom branded domains, password-protected codes and A/B split testing. Plans start free; paid tiers from $9/month.
