QRdx vs Dub

Dub and QRdx are both open source under AGPL-3.0, and both can turn a short link into a QR code with click or scan analytics. They start from opposite ends. Dub is a link management platform, used for marketing attribution and conversion tracking, where QR codes are one output among many. QRdx is a QR code platform, where design, print output and hosted mobile pages come first and links are the plumbing.

Who each tool is for

Dub suits growth and marketing teams that manage large numbers of links across channels and want to tie clicks to sign-ups and revenue. It has device and geo targeting, A/B tests, conversion tracking and webhooks, and its API is on every plan. Pro is $27 a month for 12,000 new links and 600,000 tracked events a year; Business is $81 a month.

QRdx suits anyone whose links end up printed: menus, packaging, signs, business cards and posters. Free includes 10 dynamic codes and 3 hosted pages with unlimited scans; Pro ($5/mo or $48/yr) makes both unlimited and adds routing, A/B splits, UTM tagging and custom domains; Business ($15/mo or $144/yr) adds conversion tracking, webhooks and unlimited members.

Where Dub is the better choice

• Link attribution at scale. If most of your links are shared online rather than printed, and you need to attribute sign-ups and sales to them, Dub is built for that.
• Custom domains on the free plan. Dub includes 3 custom domains for free; QRdx's start on Pro.
• Very large link volumes. Dub's higher plans are sized for hundreds of thousands of new links a year.

Key differences

• QR quality and print. QRdx has deep QR styling, AI art, a scan checker and print-ready CMYK vector export. Dub generates QR codes for its links, without CMYK print export or AI art.
• Hosted pages. QRdx codes can open hosted mobile pages. Dub links redirect to pages you host elsewhere.
• Metering. Dub limits new links and tracked events per plan. QRdx limits only Free dynamic codes and never limits scans.
• Price. QRdx Pro is $5 a month; Dub Pro is $27 a month.

Using Dub and QRdx together

You don't have to choose. Connect Dub through the QRdx integration or use the Dub.sh QR code generator: design the code in QRdx, encode the Dub short link, and keep Dub as the source of truth for destinations and attribution. Codes that encode a Dub link depend on your Dub account, while QRdx's own dynamic codes are covered by the Never-Hostage Guarantee.
