QR code and barcode scanner supporting webcam live scanning and local image file scanning

Enables users to decode QR codes and barcodes directly in the browser without needing a mobile phone or external app, using webcam or local images

User clicks the extension icon or uses the image context menu to open the scanner UI. They can start webcam scanning, paste an image from clipboard, drag & drop a local image file, or right-click an image on a web page. The extension detects QR codes/barcodes using ZBar WASM library and displays the decoded content. Results are saved to local history (up to 100 items) for later reference and copying.

Target users: General users needing to scan QR codes while browsing / Users who want to decode QR/barcodes from images on their computer / Developers and productivity users

No external services or APIs to analyze - extension is fully self-contained
ZBar WASM file is binary and not analyzed in detail

Monetization

No paid features detected

No paid features, no feature gating, no payment APIs, and no upgrade prompts found in the source code. All functionality is available without any payment. The 'pro' keyword hits are false positives from words like 'proceed' and 'Promise'. Grep for premium, payment, subscribe, stripe, upgrade all returned 0 matches.

Confidence: 100
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension works entirely locally with no authentication flows. It uses browser webcam APIs and local file reading only. No user accounts, no server-side interactions, and no login UI exist anywhere in the codebase. The 'session' keyword hits are Chrome's declarativeNetRequest.updateSessionRules API for network header modification, not user login sessions.
