QRGuard — Never let a printed QR code die

Turn already-printed QR codes on cards, menus and posters into smart redirects you can change forever

Problem

Someone printed 400 event business cards whose back QR code died when the 14-day trial expired, while the cards were still in circulation; many small merchants and makers put QR codes on packaging, menus and flyers, and when the short-link service shuts down, raises prices or expires, every printed item becomes useless.

Solution

A QR hosting service where users generate codes through our short links and can change the destination at any time; encourage CNAME to the user's own domain so redirects survive even if our service is discontinued; provide one-click export of all redirect rules as nginx/iptables config.

Users

Small merchants, restaurant owners, event organizers, indie developers and design studios who print QR codes on physical materials.

MVP

QR generator plus editable destination dashboard; custom-domain CNAME onboarding wizard; offline export of nginx redirect rules; basic scan analytics; free tier plus paid custom domains.

Revenue

Free for one custom domain; tiered subscription by number of custom domains and scan volume; lifetime license for users who only need a few fixed codes.

Why now

Short-link SaaS lifetimes are shrinking in the AI era while printed materials are still produced in hundreds or thousands, making this a sharp, urgent pain; easy for an indie developer to ship in two weeks.
