QR.

Product Introduction

1. Overview: QR. is a comprehensive, API-first platform for creating and managing dynamic QR codes. It provides a unified service that handles the entire lifecycle of a QR code, from generation and styling to intelligent routing and real-time analytics, eliminating the need for disparate tools.
2. Value: The primary benefit is operational agility and cost savings. Developers and businesses can deploy printed or digital QR codes once and update their destination, routing rules, or appearance indefinitely via API calls, without ever needing to reprint or redistribute the physical code.

Main Features

1. Dynamic Destination Updates: The core innovation is the ability to change a QR code's target URL after deployment using a simple HTTP PATCH request to the API. This transforms static print media into live, updatable links.
2. Edge-Based Intelligent Routing: Scans are resolved on a global edge network (go.qrdot.dev). Rules can be configured to redirect users based on device type (iOS/Android), geographic location, time of day, or weighted A/B tests, with password gate functionality available on all plans.
3. Full Lifecycle API: A single API spine manages minting (creation with metadata, UTM parameters, batch operations, expiry dates), printing (export to PNG, SVG, or print-ready PDF with custom styling and logos), routing, and observation (signed webhooks and REST analytics where scans don't block the redirect).

Problems Solved

1. Challenge: The high cost and inflexibility of static QR codes. Any change to a campaign, product link, or store listing requires reprinting and redistributing physical materials, leading to waste and campaign delays.
2. Audience: Software developers, growth marketers, product managers, and operations teams in e-commerce, retail, marketing, and logistics who integrate QR codes into products, packaging, point-of-sale materials, or advertising.
3. Scenario: A retail company prints QR codes on product packaging for a user manual. When the manual URL changes, instead of disposing of all existing inventory, they use the QR. API to PATCH all existing codes to point to the new documentation, saving thousands in reprinting costs.

Unique Advantages

1. Vs Competitors: Unlike basic QR generators or DIY solutions using libraries like node-qrcode, QR. provides a production-ready, integrated system. It combines generation, hosting, smart routing, and analytics into one managed service, whereas competitors often require stitching together separate services for redirects and tracking.
2. Innovation: Its technical edge is the deep integration of programmable routing logic at the edge network level and the non-blocking analytics architecture. The platform treats a QR code as a live, programmable endpoint rather than a static image, enabling complex logic like time-based offers or location-specific landing pages without app downloads.

Frequently Asked Questions (FAQ)

1. How do you update a printed QR code without reprinting it? You update the QR code's destination by sending a PATCH HTTP request to the QR. API endpoint for that specific code. The short link (go.qrdot.dev/...) encoded in the printed QR remains the same, but the API changes where that link redirects to, making the physical code dynamic.
2. What is the difference between a static and a dynamic QR code? A static QR code directly encodes a fixed URL or text. A dynamic QR code from QR. encodes a short, fixed link that points to the platform's edge network, which then performs logic (like checking rules) before redirecting to the final destination, which can be changed at any time via the API.
3. What kind of analytics and tracking does QR. provide? The platform provides scan analytics via a REST API and can send signed webhook notifications to your server for each scan event. This allows for real-time tracking of engagement, geographic distribution, device types, and the effectiveness of A/B test rules, all without slowing down the user's redirect experience.
