Your Mac's menu bar becomes a QR scanner. Click, point, done. Camera turns on only when you open it — auto-detects, copies to clipboard, opens in the right app. UPI, links, WiFi.
Uses AVCaptureMetadataOutput — hardware ISP decoder at 60fps. No lag. Plus Vision ANE fallback for blurry shots.
Menu bar app, not always watching. Green light only when popover is open. Snaps save to ~/Pictures/QRSnapBar.
Every QR is copied to clipboard instantly. Links open in your default browser, UPI in your UPI app, text stays as text. Shows which app.
Just hold a QR up — no button needed. Detects, saves photo, copies, opens. Snap button for manual control.
Detects upi:// codes. Won't accidentally open UPI in WhatsApp — warns and copies instead if your Mac default is wrong.
256KB binary. No Electron, no analytics, no network. Everything on-device. Right-click for settings, folder, quit.
