QR Relay

QR Relay is the platform behind qr-codes.ink. The code you print never changes, and where it leads can change at any time: scanners land on the new page within a minute. It is live, and open in early access.

It is running, people use it, and we still work on it.

Why it exists

A QR code on a bottle, a menu or a poster holds one address for as long as the ink lasts. When the page behind that address goes, everything it was printed on stops working. A code made with QR Relay points at an address that stays put, so the page behind it can move as often as it needs to. A code that has lost its page never shows an error: it opens a page with the owner’s name on it and a way on to their site.

What we built

A redirect service on Cloudflare’s network that answers every scan quickly, wherever it happens, and an editor where each workspace makes its codes, names them for the things they are printed on and changes where they lead. Codes can print under the customer’s own domain. The service also speaks MCP, so an AI agent can make a code and change where it leads, and a free designer turns any address into a QR code in the browser.

The launch reel0:34

What qr-codes.ink does, in the product’s own type.

How it works0:31

One printed code in three parts: the code, the address inside it, and the page it opens.

Your domain0:27

Codes that print under your own address, and stay yours.

(What it looks like)

The home page. Choose morning, lunch or tonight and the example table card changes where it leads, while the printed code stays the same.

For agents: connect an AI agent over MCP, authorize it once, and it can make and re-point codes.
