Molly

Molly is a Chrome extension that sits alongside your shopping sessions and does the comparison work automatically. As soon as you land on a product page, it checks whether the same item is available at a lower price elsewhere and offers a direct route to that offer. It also hunts for available discount codes and tries them for you, so you do not have to search coupon sites before checkout.

Beyond price, Molly focuses on buying confidence. It shows reviews and other relevant information about the shop before you complete a purchase, helping you spot merchants with a poor track record. Price alerts let you save a product and get notified when the price drops, while favourites and wishlists let you organise products and share them with family and friends — who can reserve items so you avoid duplicate gifts.

Molly is free to use and funded through affiliate partnerships. The developer is transparent that it may earn a commission when you click through to a shop or product through Molly, and that affiliate links are only used when they offer a genuine benefit such as a lower price or a valid code. The extension currently serves around 70,000 users across six languages and holds a high rating in the Chrome Web Store.
