CashCatch: best cashback, every site

See the best card + cashback stack for the site you are on. Runs on your device.

Stop leaving cashback on the table. For whatever site you're shopping, CashCatch instantly shows you: • The best card in your wallet to pay with, ranked by what each one actually earns there. • The cashback shopping portal to click through first, so you stack even more on top. • A heads-up at checkout: a small card appears automatically on supported stores so you never forget to use the right card (turn it off any time). How it works 1. Add the cards you own (just tap to select; no numbers, no linking, no account). 2. Shop normally. Open CashCatch on any store and it tells you the best card + stack. 3. Earn more on every purchase. Private by design CashCatch runs entirely on your device. Your wallet never leaves your browser, there's no account, and we never see what you buy. The extension simply downloads a public list of card reward rates: a one-way download that contains nothing about you. Honest about the numbers Card reward rates are sourced from public issuer and aggregator data and refreshed regularly. Rates and terms change often, so always confirm with your card issuer before relying on them. Affiliate disclosure CashCatch may earn a commission when you shop or apply through our links, at no extra cost to you. It never changes which card we recommend. The math is the math.
