Could you build this?
Partial The browser extension and price-comparison UI are easy to vibe-code, but a working version needs fresh price data across hundreds of stores in many countries, which means scraping at scale, affiliate feeds, or partnerships.
What it would actually take: The extension itself is standard, but the value depends on a continuously updated product-matching index covering 423 stores and marketplaces. That needs a crawler and data pipeline, product identity matching (GTIN/UPC and fuzzy matching), per-country shipping and tax calculation, and price history storage. Scale and data access, through partnerships or feeds, are the real constraints, not the code.
