Helps online shoppers in Taiwan find the lowest price for products by automatically comparing prices across hundreds of shopping/auction sites, showing historical price data to identify the best time to buy, and displaying buyer reviews to avoid low-quality products - eliminating the need to manually check multiple stores.

User browses any shopping site → extension content script detects product pages → automatically injects price comparison bar/overlay showing same product at other stores sorted by price → also displays historical price chart and buyer review carousel → user can click to visit cheapest store or view full comparison on feebee.com.tw → optional: user can right-click selected text on any page to search feebee.com.tw for that product → optional: on feebee.com.tw/member/coupon page, extension helps manage and claim available coupons.

Target users: Online shoppers in Taiwan looking to save money / Price-conscious consumers comparing products across multiple stores / Users of major Taiwan e-commerce platforms and auction sites / Users who want to avoid overpaying or buying poorly-reviewed products

All JS files are minified (e.g., ec.min.js, google.min.js) making deep logic analysis difficult - content script behavior is inferred from CSS class names, API URLs, and manifest configuration
The feebee-coupon.min.js is 79KB of minified code; the coupon claiming login flow could not be fully traced but CSS class evidence strongly suggests optional login for coupon features
Cannot verify if the feebee.com.tw destination service has its own premium/paid member tiers

Monetization

No paid features detected

No premium, subscription, billing, stripe, upgrade, or payment-related code found in any of the 15 source files. The extension is free to use. Revenue model is affiliate commissions (導購連結與聯盟計畫) from partner shopping sites. The extension rewards users with points (飛比點數 90 點, Line Points) for installing - these are bonuses, not paid features. No payment platform integration, no feature gating, no tiered pricing.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: No
Reason: Core price comparison functionality (real-time price overlays, historical price charts, buyer reviews) works without any login. The background script and content scripts inject comparison UI on shopping sites, search engines, and YouTube without authentication. However, a coupon claiming feature exists on feebee.com.tw/member/coupon (manifest.json line 76) and the CSS includes 'coupon__item-login-anchor' and 'wait-a-second__option-login' UI elements, suggesting an optional feebee.com.tw member account login is needed to claim coupons. No OAuth providers or sign-in flows are embedded in the extension itself.
