The card you should’ve
used.
Maxera quietly tells you which credit card earns the most — every time you check out. No coupons. No cookies. No spam.
Three cards. One purchase.
Which one earns the most?
You probably can’t tell — and you shouldn’t have to. The points pages are buried in PDFs. The categories rotate. The math changes mid-checkout.
That’s $5.60 left on the table on a single $80 dinner. Maxera keeps score so you don’t have to.
How much are you really leaving behind?
Pick the programs you use, set your spending level, and see the real dollar cost of leaving points and benefits unclaimed each year.

Three steps. Then nothing.
Set it up once. Shop the way you already shop. Maxera does the math in the background.
Tell us your cards
Pick from a list — no logins, no statements. We never see your bank credentials.
Shop normally
Browser extension on desktop. Mobile app for in-person taps. Maxera stays quiet until checkout.
Use the best one
One glance, one number, one card. The exact earnings — in dollars — for every card you carry.
We don’t do the things they did.
The category got burned. We built Maxera assuming you read the headlines — and assuming you’re right to be suspicious.
No credentials stored
When we connect to your bank (Phase 1), it’s read-only via OAuth — the same standard your finance apps already use. Your password never touches our servers.
No cookie hijacking
We don’t replace creators’ affiliate links with our own at checkout. We don’t set tracking cookies. The thing that broke the category isn’t in our code.
Honest comparisons
We rank by what actually earns the most for you — not by who paid us. If the best card is one we have no relationship with, that’s still the one we show.
Today the browser.
Tomorrow the tap.
The browser extension is the wedge. The point is to be the quiet intelligence layer wherever a purchase happens.
