SaaS Detective

SaaS Detective is a free Chrome extension that scans the current page’s scripts, stylesheets, and global variables to identify the SaaS tools, frameworks, and platforms powering the site. It presents the results instantly, grouped by categories such as e‑commerce, analytics, live chat, marketing, frameworks, payments, advertising, CMS, security, and hosting. The extension operates locally, collects no data, and works on any website without requiring an account.

The tool is aimed at anyone who builds, sells, or competes online. Founders and entrepreneurs can see the technology stacks of successful businesses, developers can discover frameworks and libraries without manually inspecting source code, sales and marketing teams can research prospects’ tech stacks before outreach, and agencies or freelancers can audit client sites to scope projects and recommend tools.

By providing a real‑time “stack report” with a single click, SaaS Detective turns casual browsing into a source of competitive intelligence, delivering a quick overview of the modern web stack used by any visited site.
