Different starting points
Bitly started as a link shortener; QR codes are one part of its platform, and its plans are counted in QR codes and links per month. QRGlo starts from the QR code: design, AI art, editable codes, scan stats and printing advice, with short links (Smart Links) alongside.
Editing a printed code
On Bitly’s pricing page, "Link & QR Code redirects" appears from the Core plan. On QRGlo, the 3 editable codes on the free plan can be pointed somewhere else at any time, and every code keeps redirecting whatever your plan.
