Detects the e-commerce platform or CMS used to build the website you are viewing. CMS Checker automatically identifies the e-commerce platform or CMS behind the site you're visiting, no clicking required. How it works: The extension icon changes color as soon as a CMS is detected. Click the icon for details. Built for: - Agencies and freelancers checking a prospect's tech stack before a sales call - E-commerce teams doing competitive research - Anyone curious about what platform a site was built with Privacy: CMS Checker runs entirely locally in your browser. No data is collected, stored, or sent to any server. The extension deliberately skips large non-commerce sites (Gmail, Facebook, LinkedIn, YouTube, GitHub...) so it only activates where it's relevant. A simple, free, account-free tool by Pikka (Shopify agency).
