Perkly — best card at checkout

Shows which of your Canadian credit cards earns the most rewards on the page you're paying on.

Perkly tells you which of your own credit cards to pay with, right on the cart or checkout page. Add the cards you carry, once. When you reach the cart or checkout on a supported Canadian online store, Perkly reads the order total and shows a small card in the corner of the page: the best card from your wallet, roughly how much it earns back in dollars, and how your other cards compare. HOW IT WORKS • Pick your cards on the Perkly website or in the extension popup. Perkly covers 35 popular Canadian credit cards from the big banks, Amex and store programs. • Shop as usual. On the cart or checkout page of a supported store, Perkly finds the order total and compares your cards for that store's category (groceries, drugstores, gas and so on). • Points are converted to cash-equivalent dollars, so cash back and points are compared the same way. Choose "Cash-like" or "Travel" point values. • On a store Perkly doesn't run on automatically, click "Check this page" in the popup. PRIVATE BY DESIGN • No accounts and no sign-in. • Your wallet stays in your browser. It is never uploaded to be stored. • Perkly reads only the store's domain, the order total and its currency from the page. It never reads card numbers, payment fields, cart items, names or addresses. • No ads, no tracking, no analytics and no affiliate links. Perkly is free. GOOD TO KNOW • Canada only: stores, cards and earn rates are Canadian. • Earn rates were checked against each issuer's published terms as of 2026-10-30. Rates change, so always check your card's terms. Perkly isn't affiliated with any bank or card issuer. • Results are estimates. Spending caps, promotions and how a store is coded by your card network can change what you earn. Privacy policy: https://perkly-web-five.vercel.app/privacy
