Matter QR Codes

A macOS SwiftUI app that generates print-quality, scannable Matter (smart home) QR commissioning codes — "stickers" — for any device you import from a photo of its original QR code. It can export a single sticker, export all saved devices at once, or print a multi-page contact sheet of every sticker for cutting apart. Devices are saved across launches; the app starts empty until you import at least one.
