Wappalyzer Chrome Extension: Review & How to Use (2026)

Wappalyzer Chrome extension

Wappalyzer identifies the CMS, frameworks, ecommerce platform, and analytics tools a website uses, right from the toolbar. It's best for developers, marketers, and researchers who want a quick tech-stack snapshot. The catch: it only detects what's visible in a page's code, so some backend or hidden tools won't show up.

What Wappalyzer does

Wappalyzer scans the website you're viewing and reports back which technologies it can detect, such as the content management system, JavaScript frameworks, ecommerce platform, analytics tools, and CDN. It's a quick way to understand how a site is built without digging through its source code manually, useful for developers, marketers, and competitive researchers alike.

Wappalyzer free vs paid

The Chrome extension itself is free with no premium tier mentioned in its listing, covering detection, CSV export, and light/dark mode. Wappalyzer also offers a separate web-based lookup and API service with its own pricing for bulk or programmatic use, but the browser extension for one-off lookups is free.

Is Wappalyzer safe?

Wappalyzer's listing discloses that it accesses website content, which it needs to scan pages for detectable technologies. The developer states data isn't sold to third parties and is only used for the extension's core functionality. Since it reads the pages you visit to work, that access is expected for this type of detection tool.
