Privacy-focused QR code tools

This cluster comprises QR code reader and generator tools emphasizing privacy, offline operation, minimal permissions, and security features like malicious link detection. Dated entries are sporadic, with an initial pair in January 2016, then single entries in September 2017, July 2023, December 2024, and March 2026, reflecting a long-tail niche with occasional additions. Among the traction leaders, vibe-qr-scanner shows the highest activity signal with 1 star, while Scanly and QR Scanner have 0 stars each.

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.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 7 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
