The Stackyard
How it works

Four tabs. One number.

Stackyard reads what is already on your screen and works out what a deal actually pays.

The loop

  • 🔑

    You connect

    Sign in on each site the normal way. Stackyard has no login of its own, and no code that touches a login form.

  • 🧮

    It matches

    Offers line up with deals by store, honouring minimum spends and caps. An offer that cannot fire is shown as such, not counted.

  • 💰

    It prices the portals

    Live public rates, compared per deal.

  • 📲

    It tells you

    Toolbar badge, and a Discord ping if you want one.

The alert is a running order

⚡ Profitable stack
HP OmniBook 5 Flip
HP · $679.99 · qty 1
$91.61per item, all in
1Activate the Capital One offer, $10 back
2Shop through BeFrugal · 12% back
3Buy with that card in the same tab

Order is the whole game. An unactivated offer pays zero, and a portal only earns if it is your last click before buying.

Biggest rate is not always best

Portals quote flat amounts or percentages. Which one wins depends on the price, so Stackyard compares them per deal.

On a $100 buy
BeFrugal · $15 flat$15.00
TopCashback · 2%$2.00
On a $2,000 buy
BeFrugal · $15 flat$15.00
TopCashback · 2%$40.00

It understands buying below retail

A deal that loses money on paper can still be worth it once you count the real cost. Stackyard shows that number instead of dressing it up as profit.

$599on your card
$12what it costs

1.0¢per point

Set a minimum spend target and it finds the cheapest path there. Sometimes one that pays you to finish.

What it never does

Worth being specific here, because "it reads the page" is a fair thing to be suspicious of.

No login formsIt reads offer tiles and deal listings, and has no code that touches a password field
No card numbersIt sees which offers exist, never the card itself
No balancesIt cannot see statements, which is why you enter your own minimum spend progress
No serverNone was ever built, so there is nowhere for your data to go
No trackingNo analytics, no ad tech, nothing to sell
No other sitesIt runs on your card and deal pages only, and Chrome lists exactly which

Check it yourself. The source is open, whether you install it from the Chrome Web Store or load it unpacked from the code directly. Open the files and read them. Watch your network tab while it runs. The only request it ever sends out is to a Discord webhook you create yourself, and only if you turn alerts on.
