QR Code.ioFree trial / subscriptionWhy choose QRdx over QR Code.io?
The areas where QRdx is the stronger pick. The guide below also covers where QR Code.io is the better choice.
Free for good, not for a trial
QRdx has no trial and no expiry: make static codes without an account, or sign up free for 10 dynamic codes. QR Code.io offers a free trial before a paid subscription, and its pricing page states it does not refund subscriptions.
Codes that do not depend on a subscription
QRdx static codes need no service at all, and QRdx dynamic codes keep redirecting on every plan, even after you cancel.
Developer-native
Use the REST API, or install the qrdx npm package and render styled codes in a React app with TypeScript types. QR Code.io is a hosted dashboard.
Open source
QRdx is AGPL-3.0 licensed and self-hostable. QR Code.io is a proprietary platform.
QRdx or QR Code.io: which should you use?
QR Code.io is a hosted dynamic QR platform. You sign up, start with a free trial, and continue on a monthly, quarterly or annual subscription that includes unlimited dynamic codes, unlimited scans, unlimited users and scan analytics (how many scans, when, where and on which device). QRdx works the other way around: a permanent free plan with no trial, static codes that never expire, dynamic codes that keep redirecting even if you cancel, and open-source code.
Who each tool is for
QR Code.io fits teams that want many content types behind editable codes, such as PDFs, menus, vCards, coupons, MP3s and lists of links, with hosting and analytics handled for them. Its homepage lists 18 types.
QRdx fits anyone who wants a well-designed code for a URL, Wi-Fi network, contact card, payment link or other content without signing up, anyone who wants editable codes and hosted pages without a trial deadline, and developers who want to render codes in their own app.
Where QR Code.io is the better choice
- You need one of QR Code.io's 18 content types that QRdx's hosted pages don't cover yet.
- You are happy to pay a subscription for an all-in-one tool.
Key differences
- Pricing: QR Code.io is a subscription after a trial, and its plans page says subscriptions are not refunded, so check current prices there before you start. QRdx's static codes are free; Pro ($5/mo or $48/yr) adds unlimited dynamic codes, longer analytics history and custom domains.
- Code model: QR Code.io's dynamic codes depend on its service. QRdx static codes need no service, and QRdx dynamic codes keep redirecting on every plan (Never-Hostage Guarantee).
- Design: QRdx gives separate control over 9 body patterns, 9 eye shapes and 11 eye-dot shapes, plus gradients, logos and six templates.
- Openness: QRdx is open source (AGPL-3.0) with an npm package and CLI.
Switching from QR Code.io
- Find every printed code that points at QR Code.io and decide whether to keep paying until you reprint; dynamic codes rely on the platform.
- Recreate codes in QRdx: static codes in the playground, or dynamic codes and hosted pages in the dashboard.
- Rebuild hosted content such as link lists, vCard Plus cards or PDFs as QRdx hosted pages, or host files yourself and encode that link.
- Test each code on a few phones before printing.
