About — cart.compare

cart.compare is a free price comparison engine that tracks product prices across major retailers — so you can find the best deal without opening 10 tabs.

How it works

We aggregate pricing data from retailers like Amazon, Best Buy, Walmart, Newegg, and more. Every product page shows you side-by-side prices, stock availability, and price history — all in one place. Browse by category, use search to find specific products, or check out the latest deals.

For developers

Our public API gives you access to the same pricing data we use. Build price trackers, shopping bots, or integrate comparison data into your own apps. Free tier available.
