KupokiCoupons that actually work.
Kupoki tells you which codes work on the store you're on, with their conditions, and applies the best one at checkout. No expired codes, no fine print.
Free. For Chrome, Edge, Brave and other Chromium-based browsers; Safari later.
How it works
Three steps. None of them yours.
Install the extension and forget about it. It only shows up when there's something that saves you money.
You visit a store
You see right away how many coupons work there and on what terms: minimum spend, first order only, excluded products.
You reach checkout
With one click, Kupoki tries the codes on your cart for you and tells you why each one that fails doesn't work.
We apply the best one
The winner is the code that lowers your real total the most, shipping included. If none improves your price, we change nothing.
What makes us different
We only show you what has evidence.
Most coupon extensions are full of expired codes. We measure which ones really work.
- Evidence, not promisesEvery code shows when it last worked. Codes nobody manages to use disappear on their own.
- Conditions before you payIf you're $5 away from an $8 discount, we tell you while you can still add something to your cart.
- Real savingsA "10% off" that makes you lose free shipping can save less than "$8 off". We measure the final total, not the percentage.
- We respect creatorsIf you arrive through a creator's link or a deals site, we step aside and the commission stays theirs.
Real privacy
The extension knows which sites are stores without asking us. It only contacts us when you're on one, and we never know who you are.
We only earn when you save
If you activate cashback on a store, it pays us a commission and we give part of it back to you. It never changes the order of the coupons.
Frequently asked questions
Is it free?
Yes. The extension is free and shows no ads on the sites you visit.
Which stores does it work on?
On the stores in our list, which grows every week: stores worldwide, mostly in Spain, the United States and Latin America so far. If a store is missing, you can ask us to add it from the extension. See all stores.
What data do you collect?
To look up coupons, only the name of the store you're on, and only if it's on our list. If you allow it, also whether a code worked or not, anonymously, so expired coupons disappear for everyone. Never your browsing history, your cart or your personal data.
Why doesn't a code work if it's on the list?
Many have conditions: minimum spend, first order, specific products. Kupoki reads the store's answer and tells you the exact reason for each one.
What if I already have my own code?
Use it: we detect it. If it works and isn't personal, we ask whether you'd like to share it so other people can save too. Without your "yes", it never leaves your browser.
Which languages is the extension in?
English, Spanish, German, French, Italian, Portuguese and Dutch. It follows your browser's language.
