AliCompare is a free Chrome add-on developed by alicompare.me. This handy tool allows users to search for products on AliExpress using images and check if the same product is available on other vendors.

In addition to image search, AliCompare also offers the ability to create tables for comparing products' prices, shipping costs, delivery time, and seller ratings. This feature provides users with a convenient way to analyze and compare different options before making a purchase.

It's important to note that while AliCompare is a free add-on, the developers have implemented an alternative monetization method. By activating AliExpress cashback at checkout for purchases where the user hasn't claimed their own cashback, the developers earn a small commission that helps cover the costs of maintaining the image search engine. However, users have the option to disable this feature and ensure they receive their full cashback by clicking on "Cashback Compatibility."

Overall, AliCompare is a useful tool for those who frequently shop on AliExpress and want to easily compare prices and find alternative vendors for their desired products.
