WooCommerce Products Compare Extension 

WooCommerce Products Compare will allow your potential customers to easily compare products within your store.

• Help customers find the right fit
  When trying to decide between many similar products, online shoppers want to compare prices and other features side-by-side to find the product that’s right for them.
  By adding the option to compare products, store owners can help customers make the right choice. If you’re running a large store, with many similar products, giving customers the option to compare can make a big difference.
• Let customers select products to compare
  With this extension, customers will see the option to compare products directly on category pages. Customers can select the options they’re considering to see important details side-by-side.
• Show detailed comparison tables
  Once customers have selected a set of products to compare, they can see a detailed chart showing price, ratings, stock level and descriptions.
• Add a comparison option anywhere on your store
  It doesn’t stop at the category page – any page can include the option to compare products. The products a customer has already viewed will stick around, so they can easily add more options as they find them across your store.
