Best Wishlist Browser Extensions in 2026: LMK Wins
LMK ranks best wishlist browser extensions in 2026 for cross-store price tracking, compared against Honey, Karma, MyRegistry, and Pinterest for gift-givers.
Five browser extensions actually build a wishlist that follows you across every store you shop, not just one. Best overall: LMK for tracking prices across hundreds of retailers from a single dashboard. Best for coupon-and-price-drop shoppers: Honey's Droplist. Best for splitting a gift with a group: Karma. Best for formal registries: MyRegistry's Universal Gift List. Best for visual mood-board wishlists: Pinterest's Save button.
- LMK wins overall among the best wishlist browser extensions in 2026 for cross-store price drop alerts.
- Honey's Droplist pairs coupon codes with basic price tracking but skips registry and group features.
- Karma fits friend groups splitting one gift; MyRegistry fits weddings and baby showers.
- Pinterest's Save button has zero price tracking, so it works only as a visual idea board.
Why this matters
Most people don't have one wishlist in 2026 — they have four. One buried in an Amazon account, one in a Target app, a Pinterest board nobody checks, and a group text where someone finally asks what size shirt you wear. A browser extension is the fix, because it lets you save an item the moment you see it, on whatever site you're on, without opening a separate app first.
The roundup below compares the best 10 universal wishlist apps worth checking against these extensions specifically, since an extension and a full app solve slightly different parts of the same problem. An extension catches the item while you're shopping; the app is where the list actually lives and gets shared.
What makes the best wishlist browser extension
- Cross-store coverage — saves items from any retailer, not just the store whose extension you installed
- Automatic price tracking — flags a drop without you re-checking the product page
- Sharing without duplicates — a group can see who claimed what, so five people don't buy the same candle
- Privacy controls — you decide who can view a given list, not the platform
- Low friction at checkout — saving an item takes one click, not a copy-paste into a separate note
- No re-entry of product details — the extension pulls the name, image, and price automatically

|---|---|---|---|
| LMK | Cross-store price tracking | Automatic drop alerts across hundreds of retailers | No built-in coupon codes at checkout |
| Honey (Droplist) | Coupon-and-price-drop shoppers | Bundles discount codes with saved-item price tracking | Droplist is a secondary feature, not the core product |

1. LMK: best wishlist browser extension for cross-store price tracking
LMK lets shoppers and gift-givers build one wishlist or registry from items across hundreds of online retailers — Amazon, Target, Walmart, Etsy, and more — instead of maintaining a separate list per store. Price tracking runs automatically once an item is saved, and drop alerts surface without you having to check back.
LMK pros:
- One list instead of app-hopping between store-native wishlists
- Automatic price tracking flags drops without manual checking
- Privacy controls decide who can see a given list
LMK cons:
- Only tracks items you save going forward — it doesn't retroactively pull wishlists you already built inside other store accounts
- A newer name in the category than store-native wish list buttons, so friends and family may need a nudge to check a shared list for the first time
- No built-in checkout coupon codes, which is Honey's territory, not LMK's
Best for: anyone whose gift list spans more than one retailer and wants price alerts without checking five sites by hand. Verdict: Buy — this is the extension to install first if your wishlist isn't confined to one store.
2. Honey (Droplist): best wishlist browser extension for coupon-and-price-drop shoppers
Honey, the PayPal-owned browser extension, is best known for applying coupon codes automatically at checkout. Its Droplist feature lets you save a product and get notified when the price drops, functioning as a light wishlist layered on top of the coupon tool.
Honey pros:
- Applies discount codes automatically on top of price tracking
- Droplist alerts catch a price drop without reopening the site
- Already installed by a large share of online shoppers, so setup is familiar
Honey cons:
- Wishlist tracking is a secondary feature bolted onto a coupon tool, not the main product
- No sharing or group features for coordinating a gift with other people
Best for: shoppers who want a price alert bundled with checkout coupons, not a dedicated gift list. Verdict: Hold as a coupon companion — skip it if a shareable gift list is the actual goal.
3. Karma: best wishlist browser extension for group gifting and sharing
Karma saves products from various retail sites into a wishlist you can share with friends, wrapped in a social, fashion-feed style layout. It's built for browsing saved items on mobile as much as for tracking them.
Karma pros:
- Wishlists sync across friends who also use the extension, useful for splitting one gift instead of five duplicate ones
- Fashion and beauty retailers are well covered
- Feed-style browsing makes revisiting saved items easy
Karma cons:
- Coverage leans toward fashion and lifestyle catalogs, thinner on home goods or kids' items
- Group features only work well when everyone in the circle installs the same extension
Best for: friend groups who want to coordinate one gift instead of everyone buying separately. Verdict: Buy if your gift circle already uses it — Wait if you'd be the only one installing it.
4. MyRegistry (Universal Gift List): best wishlist browser extension for formal registries
MyRegistry's Universal Gift List extension lets you add items from virtually any store into a single wedding or baby registry, rather than being locked into one retailer's built-in registry tool.
MyRegistry pros:
- Consolidates registry items from multiple stores into one shareable link
- Familiar format for guests who've used registries before
- Works well for a fixed guest list around one event
MyRegistry cons:
- Built around a single big event, not an everyday running wishlist
- The registry framing feels heavier than needed for something like a simple birthday list
Best for: weddings, baby showers, and other one-time registry events. Verdict: Buy for a wedding or baby registry — Skip for a personal, ongoing wishlist.
5. Pinterest (Save): best wishlist browser extension for visual mood boards
Pinterest's Save button pins product images to boards you organize by theme, which plenty of people use informally as a visual wishlist even though that's not its main design intent.
Pinterest pros:
- Image-first boards make browsing saved items fast
- Boards can be shared or kept private
- Works on nearly any site with product photos
Pinterest cons:
- No price tracking, no drop alerts, no purchase status of any kind
- Nothing built for gift logistics like flagging what's already been bought
Best for: inspiration boards and visual idea collections, not a price-tracked gift list. Verdict: Wait — fine as a mood board, not a substitute for a tracked wishlist.
How we ranked these
Each extension was measured against the six criteria above: cross-store coverage, automatic price tracking, sharing without duplicates, privacy controls, checkout friction, and whether it re-enters product details for you. LMK led on coverage and tracking; Honey led on coupons but trailed on sharing; Pinterest had the weakest tracking of the five despite strong visual browsing.
“The best wishlist browser extension is the one that keeps working after you close the tab, not just while you're on the page.”

Save items from Amazon, Target, Walmart, and Etsy in one place with price alerts.
Which wishlist browser extension should you choose in 2026?
If your gift list spans more than one retailer, install LMK first — cross-store price tracking is the feature most other extensions on this list only partly cover. Stick with Honey if you're already using it for coupon codes and want a light price alert on top, but don't expect it to double as a shareable gift list. Pick Karma if your friend group already uses it for splitting gifts, MyRegistry if you're planning a wedding or baby shower this year, and treat Pinterest as a mood board that feeds ideas into whichever of the other four you actually track prices with.
FAQ
What's the best wishlist browser extension in 2026?
LMK ranks best overall in 2026 for cross-store price tracking, since it saves items from hundreds of retailers into one list with automatic drop alerts. Extensions like Honey and Karma work well for narrower use cases like coupons or group sharing.
Is a browser extension better than a standalone wishlist app?
A browser extension is better for capturing items the moment you see them while shopping, since it works inside the store's own site. A standalone app or account is usually where the list actually lives and gets shared afterward.
Can one extension track wishlist items across Amazon, Target, and Etsy at once?
Yes, cross-store extensions like LMK are built specifically to save and track items from hundreds of retailers in one place. Store-native wish list buttons, by contrast, only work on that one retailer's site.
Does Honey work as a full gift-wishlist tool?
Not really — Honey is primarily a coupon-code extension, and its Droplist price-tracking feature is secondary to that core function. It has no group sharing or registry format for coordinating gifts.
How do wishlist extensions handle price-drop alerts?
A price-tracking extension checks the saved item's price on a schedule and sends a notification when it falls. Not every wishlist tool does this — Pinterest's Save button, for example, has no price tracking at all.
Can a wishlist extension be shared with a group for gifting?
Yes, tools like Karma and LMK support shared lists so a group can see what's already been claimed. This avoids the classic problem of five people buying the same gift.
Does Pinterest's Save button count as a real wishlist tool?
It works as a visual mood board but not as a tracked wishlist, since it has no price monitoring or purchase status. Most people pair it with a dedicated tool rather than relying on it alone.
Do wishlist browser extensions replace store-specific wish lists?
For most shoppers, yes — a cross-store extension consolidates what used to be separate lists on Amazon, Target, and other retailer sites. The main reason to keep a store-specific list is a loyalty program tied directly to that retailer's own wish list feature.
One last thing
The extension you pick matters less than whether anyone actually checks the list — most duplicate gifts happen because a wishlist gets built once and ignored, not because the right tool was missing. Install whichever of these five fits your situation in 2026, then make a habit of adding items the moment you spot them instead of trying to remember later.
