Bitly is a URL shortener and QR code generator with click analytics, the tool most people default to when they need a branded short link.
It solves one narrow job: shortening and tracking links for campaigns run in print, social posts, or ads where a long URL doesn't fit or can't be measured. It isn't a suite like the other tools here, just a focused utility.
Anyone running print, social, or paid campaigns who needs to brand and track click-throughs on a short link.
Free plan is thin: 5 short links and 2 QR codes a month, no click analytics on those free links, and every free link now shows an interstitial ad page before redirecting. Fine for testing, not for regular campaign use.
