Unkillable Tools · No.1

QR codes that expire keep working. Forever.

The QR industry's business model is a redirect you rent. Print a code, stop paying, and the sign in your window becomes a dead link. Unkillable QR generates static codes — the destination is encoded in the pattern itself, so there is no redirect to switch off.

Why printed QR codes die

A "dynamic" QR code doesn't contain your link. It contains their link, which then forwards to yours — and forwarding is a service they can stop providing.

The trap is the trial

Codes generated during a free trial are usually dynamic by default. You print 5,000 menus, the trial ends, and every one of them stops resolving.

📊

Scan analytics are the hook

The tracking that makes dynamic codes attractive is exactly what requires their server in the middle. The feature and the failure are the same mechanism.

Print outlives software

A sticker on a piece of equipment might be scanned in 2036. No SaaS pricing page should get a vote on whether it still works.

Same principle, different artifact

Unkillable QR and the Unkillable Calculator solve the same structural problem in two different categories: you should be handed the thing you made, not a subscription that renders it.
