RivalSonar vs Koala Inspector
As of November 2026, Koala Inspector is a Chrome extension for researching Shopify stores. Open a store, click the extension and it shows the store's theme, apps, products and best sellers, with sales estimates and traffic data on paid plans, alerts when watched stores add products and CSV or Excel exports. It covers only Shopify and has a free plan. RivalSonar also has a Chrome extension, in beta, but is built around a web app with a store explorer, ad library and hourly sales tracker across several platforms. RivalSonar is new. While our crawler fills the real database, the site runs on generated sample data, and sample stores use .example domains.
