Adds price comparison, price history charts, and price drop alerts to Tiki, Lazada, and Shopee product pages — all in one panel, without opening extra tabs. Smarter shopping starts the moment you install DataScraper VN. Browse any supported product page and instantly see prices from all three major Vietnamese e-commerce platforms side by side. ✓ Instant Price Comparison See prices from Tiki, Lazada, and Shopee directly on the product page you're viewing. DataScraper VN automatically identifies the product and fetches prices from the other two platforms in under 2 seconds. The lowest price is highlighted clearly, along with how much you save by switching platforms. ✓ Price History Charts View daily price history for up to 7 days (Free) or 90 days (Pro) on every supported product. Stop falling for fake flash sales — the chart shows you whether today's "discount" is genuine or just a price that was artificially raised and then restored. Includes automatic detection of suspicious price movements with on-chart annotations. ✓ Price Drop Alerts Set a target price on any product and receive a Chrome notification the moment any supported platform drops below your threshold. Alerts run silently in the background. One click on the notification takes you directly to the product page on that platform. Free plan includes 1 active alert; Pro is unlimited. ✓ Watchlist Dashboard Save products to a watchlist and monitor all of them from a single dashboard. See the current best price, recent price movement, and alert status for every tracked product in one view. Export to CSV with Pro. ✓ Built for the Vietnamese Market Understands Vietnamese product naming conventions across platforms. Correctly reads active Shopee Flash Sale prices, Lazada platform voucher pricing, and distinguishes official store listings (Shopee Mall, LazMall, Tiki Trading) from third-party sellers. Supported platforms: Tiki (tiki.vn), Lazada Vietnam (lazada.vn), Shopee Vietnam (shopee.vn). -> No Account Needed: Install and start comparing prices immediately. Free plan requires no registration. -> Seamless Integration: The comparison panel appears directly on the product page. No new tabs, no separate website to visit. -> Your Data Stays Local: All data — watchlist, alert settings, price history — is stored locally in your browser using chrome.storage.local. No personal data is collected or transmitted to any server. We follow Chrome's minimum permissions policy and only request the following: - Access to tiki.vn, lazada.vn, shopee.vn: Required to read product information and fetch prices from the three supported platforms. - "storage": Stores your watchlist, alert settings, and cached price data locally in your browser. - "notifications": Sends a Chrome notification when a product price drops to your alert threshold. - "alarms": Runs periodic background checks to monitor alert prices. Has no impact on browser performance. DataScraper VN does not read passwords, payment information, or browsing history. It does not activate on any website other than the three platforms listed above. Privacy policy: datascraper.vn/privacy Support: datascraper.vn/support
