Inspiration

Most web-based QR code scanners require native mobile apps or upload sensitive camera feeds to remote cloud servers. We engineered a 100% client-side decoding suite using WebAssembly and HTML5 Canvas that executes entirely inside the user's browser with zero server telemetry.

  • Instant Camera Scanner: High-speed webcam and mobile camera decoding with auto-focus.
