KeepCart: Stop Coupon Leaks

We run Planet Mujo, a pain relief brand where margins matter, and KeepCart has instantly become one of the most important apps on our Shopify store.

Our main reason for installing it was to stop coupon extensions like Honey and Capital One Shopping from scraping and auto-applying discount codes we never intended to be public. KeepCart blocks these extensions perfectly. Before this app, we were constantly fighting margin leakage from leaked codes, unauthorized discounts, and customers stacking promos. Now, problem solved.

Setup took only a few minutes, and everything worked right out of the box. No theme conflicts, no site slowdown, no complicated configurations. Their support team is also excellent, fast responses and incredibly helpful. If you're tired of coupon extensions eating into your margins, KeepCart is the fix. Simple, effective, and absolutely worth it.

Highly recommended by the Planet Mujo team.

Great tool to help keep tabs on discount codes being used, see if anything has been leaked, and generally monitor discounts. The app dashboard is also very clear and easy to understand.

If for no other reason than being able to track codes out in the wild / leaked and get updates on those, you should consider this app. It's a great tool to fight back against all of the code injection sites, especially if you work with influencers, etc and want better directional data on actual code efficacy there.

Extremely helpful insights into how our customers are finding and using discount codes.

We were able to quickly spot coupon codes that had leaked to extensions and deal sites and shut them down before they caused more damage. It gave us visibility we didn’t have before and made it much easier to protect our checkout and margins. Simple to use and genuinely useful.

KeepCart has been great in helping us monitor and prevent code leaks. It’s already identified several incidents early on, and we’re exploring code blocking to take our protection even further. The team’s responsiveness and support have made implementation seamless and efficient.

Loving this! Being able to keep our offers exclusive helps to keep my community engaged and loyal. Game changer!

If you are tired of seeing your profit margins eroded by coupon extensions like Honey, Capital One Shopping, and Rakuten, KeepCart is an absolute game-changer.

Before installing this app, we struggled with discount codes—intended only for specific influencers or email segments—leaking onto the web and being auto-applied at checkout. KeepCart solved this immediately. It effectively blocks over 150 different coupon extensions and even alerts us if a code has been leaked to a third-party site so we can take action.

The dashboard is incredibly clean and provides great insights into how many 'leaks' are being prevented in real-time. It’s also been fantastic for stopping affiliate and reseller abuse by preventing duplicate account fraud.

The setup was quick and easy. If you’re serious about protecting your brand’s value and keeping your margins intact, this app is a must-have!

Game changer! We have a fairly large influencer program and have seen an unusal spike in discounts lately due to promo codes. While that's to be expected, there was no way to know all the places the codes lived. Now with KeepCart we can easily tell whose code needs to be updated, all the places the codes are leaked, do we need to block them, etc. The details on this app are incredible. The platform is user friendly and I can tell everything I need to know as soon as I log on. It's a must-have tool for your business!

The app does exactly what it says and was easy to set up.
