Both doors run on the same edge brain - the same ~50 ms redirects, the same routing rules, the same privacy posture. Pick the one shaped like your problem.

Dynamic QR codes with a full designer - shapes, gradients, logos, frames - always paired with a live scan-safety check, because a reprint costs real money. Links behind the codes can be edited and re-routed after printing, and they never 404: a paused link resolves to a branded page, not a dead end. Free static QR codes encode your content directly and are yours forever - there is no trial to lapse.

Traffic-quality analytics for marketers and affiliates. Every click on a Kilo Trace link is classified at the edge - datacenter, VPN or proxy, likely human - with breakdowns per link and per sub-ID, so you can see which traffic source is real and which invoice to question. Routing rules (geo, device, weighted splits, schedules) evaluate inside the same redirect. Free tier included.
