Paste a product URL (Amazon, Best Buy, Target, Walmart, Newegg, more). Price tracked every few hours. Alert when it drops past your target. Historical chart so you know if 'on sale' is actually a deal or just a rebranded regular price. Wishlist you share with family. No ad-network upsells.
Product URL from major retailers → price auto-scraped every 6 hours. Product name, image, current price, sale price, availability.
Set a target price per product. Email or SMS when it hits. Alerts include the full price history so you can judge if 'sale' is for real.
Per-product line chart of price over time. 90-day, 1-year, all-time. Flag the 'inflated-before-sale' trick when retailers do it.
Wishlist categories (Christmas, birthdays, house). Share read-only link with family or friends. Product status (still tracked, bought, out of stock) visible.
Your wishlist isn't Amazon's affiliate-link goldmine. Nobody selling you more stuff based on what you want. Data's yours.
Flask + SQLite. Runs on a laptop or $5 VPS. Scraping respects robots.txt + rate limits (1 query / 6hr / product is plenty).
Hosted plans are early-access. Self-host today; email tim@dangercorn.net to join the waitlist.
