Subscriptions are not the only thing QRever competes with. A small pay-once market exists, and it is the fairer comparison — those products make the same promise QRever does, so the question stops being “rent or buy” and becomes “which one to buy”.
QRever is not the cheapest way in. One permanent dynamic code costs $19 here, against $15 at OwnQR — and $150 at Scanova, the most expensive.
Where QRever is the cheapest is the page behind the code. A QRever QR Page — a menu, business card, links, event or reviews page, hosted and editable — costs $39 once. Of the other products here, only Lifetime QR Codes and Permanent QR Codes host a page behind a code, from $49.
