Modern, privacy-first QR code generator, customizer, and scanner.
No analytics. No network. Just your codes.
QR code is a 35-year-old public domain standard. The idea that companies can charge you for generating a QR code — or worse, track you while doing it, is absurd.
The QR code industry has become something completely different from what its inventors intended. Most online QR code generators work the same way: they let you create a code, then track you, log your data, force you to create an account or serve you ads. They’re “free” because you are the product. Capitalism has managed to ruin even the most basic digital tools. Every feature must be behind a paywall. Every interaction must be tracked and monetized.
Curium rejects this. Some things should just work. Some things should be free. Some things should respect your privacy by default — not as a premium feature. Unlike the others, Curium offers a modern, clean UI/UX with no ads, no bloat, no spyware, and no hunger for your data. As it develops, it continues to ship every feature an ideal QR tool should have.
With official releases for Android, Windows, macOS, Linux, CLI, Web, and eventually iOS, Curium aims to deprecate and make every other QR tool obsolete — bringing an end to decades of QR capitalism.
Preview builds may feel rough or unpolished and may contain bugs. They are intended for early testing and feedback.
