QR codes that stay editable after you print them.

QRDock is a self-hosted QR generator where every code is a short link you control. Print it, then change the destination whenever you want — no reprint, no subscription, no account wall.

Why

• Retargetable: change a printed code's destination anytime — the QR never goes stale
• Scan analytics: per-link counts and a 14-day chart
• PNG + SVG export, plus an instant anonymous endpoint /qr.png?text=...
• Tiny: Python + FastAPI + SQLite, ~50 MB RAM, one docker run
• MIT: read it, audit it, change it, ship it

Deploy in one command

docker build -t qrdock .
docker run -d -p 8000:8000 -v qrdock-data:/data qrdock

Open http://localhost:8000, register, create a link, print the QR — retarget it forever.

QRDock is the free member of the Grand Line fleet — 20 production micro-SaaS tools (feedback boards, forms, status pages, booking, analytics) sold as a one-time source bundle with KYC-free crypto checkout.
