StackEasy — Smart Card Picker & Flight Watch

Best card for any checkout, plus price-drop alerts on flights you booked. Free to install; 14-day trial, then $25/mo.

StackEasy makes the cards you already own earn more — for free, without ever seeing your bank login. At checkout, it shows the single best card to use and exactly why. Track a flight you already booked and it catches price drops so you can claim the difference. And it keeps you off the wrong card with 0% APR and utilization alerts. No coupons, no link hijacking, no account required to start. ━━━━━━━━━━━━━━━━━━━━ BEST CARD AT EVERY CHECKOUT ━━━━━━━━━━━━━━━━━━━━ Land on a product or checkout page and StackEasy ranks your cards for that purchase in real dollars, not a vague "rewards rate." It values points honestly (Chase UR at 1.75¢, not a flat 1¢) and shows the math, so you can see why the top pick wins. It even factors a card about to lose its 0% APR window or sitting near its limit because that's a losing swipe no matter the rewards. Build a wallet from thousands of cards with no account needed. 900+ cards rank instantly offline; 450+ merchants recognized. ━━━━━━━━━━━━━━━━━━━━ FLIGHT PRICE DROP WATCH ━━━━━━━━━━━━━━━━━━━━ Add a flight you already booked. StackEasy re-prices the same seats and times and tells you when the fare genuinely drops. Southwest included. Fare-recovery services take ~25% of what you get back. This is free, and you keep all of it. ━━━━━━━━━━━━━━━━━━━━ NEVER THE WRONG CARD ━━━━━━━━━━━━━━━━━━━━ Connect your StackEasy account (read-only) and see 0% APR deadlines, utilization warnings, payment-due reminders, and the card benefits you're paying for so spend never lands on the card that costs you. ━━━━━━━━━━━━━━━━━━━━ BUILT ON TRUST — THE PART OTHERS GET WRONG ━━━━━━━━━━━━━━━━━━━━ • We never see your bank login. Signing in connects your StackEasy account only — never a bank credential. • No link hijacking. We never rewrite your links or take a commission on your purchases. (That's how coupon extensions actually make money. Not us.) • On-device by default. Page detection happens in your browser; the pages you visit are never sent anywhere. • No analytics, no browsing history, no selling your data. Ever. Free to install. Full features need a StackEasy account: 14-day full-access trial, then $25/mo. Privacy policy: https://www.stackeasy.ai/extension/privacy/
