About QR.

QR. is the developer API for dynamic QR codes. Create codes over HTTP, export PNG/SVG/PDF, host edge short links on go.qrdot.dev, and change the destination anytime with a PATCH — no reprint.

Compose one spine for most use cases: mint → print → live link → route → observe → brand. Edge rules cover device, country, time, password gates, and A/B. Scans fire signed webhooks without blocking the redirect.

Official clients for Node, Python, Go, PHP, Ruby, plus a CLI. Free plan includes the full API (20 dynamic QRs/month, unlimited scans). There’s also a free no-signup generator at /create/ so anyone can try a living QR in seconds, then claim it into a dashboard and graduate to the API.
