QR code paper backups
This cluster consists of tools that convert secrets or files into QR codes for printable, offline paper backups, including key-splitting and reconstruction schemes. The dated history is too thin to read a shape from—only two dated entries exist before the index start, and the rest predate the index or are undated. Traction leaders are paper-age, QuorumPony, and qr-backup, each with 0 stars, so no product shows meaningful activity.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
