What it does

Built for the Linux desktop

CoBang is a small, native GTK application that handles everyday QR tasks without pulling in a web stack or sending data anywhere.

  • Scan from webcam

    Point your laptop camera at a code. CoBang reads it live and copies the result to the clipboard.

  • Scan from image

    Drop or open any PNG, JPEG or WebP file. CoBang finds and decodes every QR code in it.

  • Generate codes

    Create QR codes for plain text, URLs, email, phone numbers and WiFi networks, then save them as images.

  • WiFi made easy

    Scan a WiFi QR code to connect instantly, or generate one from your saved networks to share with guests.

  • Dark mode

    Follows your system theme. Both light and dark variants are polished and readable.

  • Privacy first

    All scanning and generation happens locally. No analytics, no accounts, no network requests.
