Extract a Competitor's Product Catalogue
Pull structured product data from a competitor's catalogue — names, prices, descriptions, and images — for competitive analysis.
Monitor Product Price Changes
Track price changes across a product catalogue over time and alert when prices drop, increase, or products go out of stock.
Tool
Pricing decisions get made on stale data. By the time your team notices a competitor cut prices or a key product went out of stock, you have already lost margin or missed purchase windows. The problem isn't awareness — it's the gap between when the change happened and when you found out.
Catalogue Scraper extracts current prices across a full product catalogue and returns the data in a consistent schema. Running it on a schedule and diffing against the previous extraction surfaces every price change and stock status update the moment it appears on the site — not days later.
Pricing teams, buyers, and e-commerce managers use this to respond to competitor price changes before they affect conversion, catch restocks on high-demand products, and maintain current price parity reports.
