QRdx vs QR.io

QR.io and QRdx both make dynamic QR codes you can edit after printing, with scan statistics and hosted mobile pages. QR.io sells a single plan with unlimited codes after a 7-day trial. QRdx has a free plan and paid plans from $5 a month, and its dynamic codes keep redirecting whatever plan you're on.

Who each tool is forCopy Anchor Link

QR.io suits a team that wants unlimited codes on one plan and is ready to pay once the trial week is up. The plan costs $39.99 a month or $350 a year and includes unlimited dynamic and static codes, unlimited scans, custom landing pages, scan statistics, bulk creation, API access and 5 team members. It lists 14 dynamic types, such as business pages, coupons, menus and MP3s, and 10 static types, including PayPal and Bitcoin payments.

QRdx suits people who want to start free and pay monthly, if at all. Static codes are free and need no account. The Free plan adds 10 dynamic codes and 3 hosted pages. Pro ($5/mo or $48/yr) makes both unlimited, and Business ($15/mo or $144/yr) adds unlimited team members and white-label pages. Developers get the REST API on every plan, and the whole app can be self-hosted.

Where QR.io is the better choiceCopy Anchor Link

• You want the site in your language. QR.io is available in English, Spanish, Portuguese, Italian, French and German. QRdx is English only for now.
• You want a refund guarantee. QR.io's refund policy promises a full refund if you ask within 7 days of your first purchase. QRdx looks at refund requests case by case.
• You run a non-profit. QR.io's help center says it has special plans for non-profits, arranged through its support team.
• You'd rather not choose between tiers. QR.io's one plan comes with unlimited codes, bulk creation, the API and 5 team members.

Key differencesCopy Anchor Link

• What happens when you stop paying. QR.io's help center says that when the 7-day trial expires, "Dynamic QR codes will be paused" until you upgrade, and static codes "will work forever." Its refund policy says that after you cancel a paid plan, "your QR Codes will go into paused mode" until you subscribe again. We checked both pages on 10 November 2026. On QRdx, dynamic codes keep redirecting on every plan, including after a cancellation.
• Price. One person with a few codes pays nothing on QRdx. On QR.io the cheapest option after the trial is $39.99 for one month.
• Getting a code. QR.io asks you to create a free account before you can download any code. The QRdx static generator works without an account.
• Developer access. QR.io's API comes with its paid plan and allows 2,000 requests a month. The QRdx REST API allows 1,000 requests a day on Free and 10,000 on Pro, and QRdx also has an MCP server, a React library on npm and a CLI.
• Openness. QRdx is open source under AGPL-3.0, so you can check how scans are counted or run your own copy. QR.io doesn't advertise its source code.

Switching from QR.ioCopy Anchor Link

1. Keep your QR.io plan active until the codes you've printed are replaced. QR.io's dynamic codes redirect through QR.io, so they depend on that plan. Static QR.io codes keep working without it.
2. Get a list of your codes from QR.io's List API, which returns 100 codes per page, or write each code's name and destination in a spreadsheet. Import the list into QRdx to make them dynamic QRdx codes.
3. Rebuild hosted pages in the QRdx page editor, and test each new code on a couple of phones before printing.
