Kelkoo is a price comparison platform for online shopping, where consumers can compare offers from web shops. For merchants it provides an advertising service that makes their products visible in the comparison pages. Kelkoo also offers an API that other comparison sites use for product data. The service is active in several European countries, including France, Germany, Italy and the Netherlands, and is delivered as a web platform without installation.
Kelkoo Group is headquartered in London, United Kingdom, and has been owned since 2008 by the British private equity firm Jamplant Ltd. In 2016 the group acquired LeGuide and adopted the Kelkoo Group name. The United Kingdom lies outside the European Union, so European organisations using the service should review the processing terms and the hosting locations of customer data with the vendor. Kelkoo is not open source.
