Coupon Chrome Extensions (2026): 8 Auto-Apply Tools Compared

Hunting for a discount code in another tab, finding three that don't work and giving up is a familiar way to waste ten minutes. These extensions do the hunting at checkout instead, so you're not copying codes that have already expired.

The eight below are listed alphabetically, in no particular order, and the details come from the Chrome Web Store listings. If you've wondered what goes on behind the best-known one, my explainer on how Honey works walks through it.

How these coupon extensions were picked

Each tool is a Chrome extension whose listing says it finds or applies coupon codes. From every Chrome Web Store listing we noted the publisher, users, rating and number of ratings, and the last updated date, as of Oct 2026. Nothing has been ranked. The free plan column says Yes only where the listing's own text says the extension is free, and Not stated means it doesn't say.

Shopilo	Coupon finder	Finding and applying coupons at checkout	Not stated

Eight coupon extensions that apply codes at checkout

BeFrugal

Best for: Shoppers who care most about cash back, as its listing claims over 5,000 stores and restaurants alongside automatic coupons.

Coupert

Best for: Automatic coupon finding with cash back rewards on top, highly rated on its listing by a large number of shoppers.

Mino

Best for: Highly rated checkout savings with the data line shown on its listing, which says the extension is free.

Mojo

Best for: Trying a very small coupon tool that its listing says is free, though the last update was January 3, 2024.

PayPal Honey

Best for: Anyone happy to shop with PayPal's own extension, as PayPal Inc. is the developer named on its store listing.

Pie Shopping

Best for: Pairing coupons and cash back with an AI side panel, from pie.org, the same group that makes an ad blocker.

RetailMeNot

Best for: Finding promo codes and cash back as you shop, from a listing that says the extension is free to install.

Shopilo

Best for: A highly rated coupon finder from DontPayFull SRL, with a much smaller user base than the big names here.

Coupon finder or cash back tool

Every extension here looks for coupon codes and tries them at checkout. The difference is what else they bolt on. Several listings also mention cash back, one adds an AI side panel, and a couple stick to codes and nothing more.

This page only covers what the listings say, and it doesn't go into anyone's cash back rules. Cash back terms vary by tool and by shop, so read the terms on the tool itself before you count on any money coming back.

Users, ratings and updates for each one, as of Oct 2026

Straight from the Chrome Web Store, so expect them to move.

The most installed coupon tool has the lowest rating

This is the one people don't expect. The extension with by far the most users here, 12,000,000, has the lowest rating in the group: 2.2 from 179.6K ratings. The highest rated ones sit at 4.9 with a fraction of the users. A famous name tells you it's popular, not that people are happy with it, so read the rating and the count together.

Privacy is the other thing to check. Only two of the eight listings carry the line saying the developer will not collect or use your data. A coupon tool runs on the shops you visit and at checkout, so open the Privacy practices box before you install. And one listing here shows no update since January 3, 2024.

Which coupon tool for which shopper

• You want codes tried automatically and nothing else: pick a plain coupon finder.
• Cash back matters as much as codes: pick one whose listing mentions cash back, then read its terms on the tool itself.
• You already shop with PayPal: the extension with PayPal Inc. as developer is the obvious one to look at, rating and all.
• Privacy comes first: pick one that shows the will not collect or use your data line on its listing.
• You like extra help while you browse: pick the one with an AI side panel for deals.
• You shop at restaurants as well as online stores: pick one whose listing names restaurants.

Before you let an extension into your checkout

1. Install one coupon tool at a time, so you know which one is doing the work.
2. Check the order summary after a code is applied, so you can see the discount yourself.
3. Read the cash back terms on the tool itself before you count on any money coming back.

My advice on coupon extensions

Pick on rating and rating count together, then the privacy box, then the last update. A tool with a high rating from thousands of people is a safer bet than a famous one people complain about, and an extension that hasn't been updated in years is best left alone at checkout. It's your card details on that page, after all.
