## What it is
A progressive web application that scans and decodes QR codes and barcodes directly from the browser using the device camera or uploaded images. All decoding happens locally on the device, with offline support via PWA caching.

## Use cases
- scan qr codes from browser without installing an app
- decode qr code from a saved image or screenshot
- offline qr code scanning on mobile
- privacy-friendly qr scanner that doesn't upload images
- scan barcodes with phone camera in chrome or safari

## When to choose
- you need a free, no-install QR/barcode scanner that works in any modern browser
- privacy matters and you want decoding to happen entirely on-device
- you want an installable PWA that works offline

## When to avoid
- you need a programmatic QR generation or scanning library to embed in your own app
- you need active development or recent updates - the repo points to a successor project
- you need server-side bulk QR code processing

## Facets
- artifact type: application
- maturity: maintenance
- function: computer-vision, image-processing
- domain: web-development, developer-tools
- platform: browser, cross-platform
