See what any website is built on — CMS, frameworks, analytics, ad tech, hosting. One click. No account, no limits. 100% local. See what any website is built on — in one click. StackPeek reveals a website's technology stack in a clean side panel: its content management system, front-end framework, e-commerce platform, analytics, advertising tools, hosting, and more. Each detection shows the technology's logo, its version where available, and the exact evidence behind it. Built for SEO and marketing professionals researching prospects and competitors, developers curious about how a site is built, and agencies qualifying leads. WHY STACKPEEK IS DIFFERENT • 100% local. Detection runs against the page you're already viewing, inside your browser. The only network request it makes is reading the current page's own response headers. There's no server, no account, and no telemetry. • No lookup limits. Because there's nothing to meter, you can check as many sites as you like — free. • Transparent. Click any result to see which signals matched, so you can trust what you're seeing. • Practical. Copy a clean summary of a site's stack for your notes, and keep a local history of the sites you've checked — stored only on your device. HOW IT WORKS Detection runs only when you click the StackPeek icon — never automatically. StackPeek reads the current page's markup, scripts, and response headers, matches them against its built-in database of technology signatures, and shows the results grouped by category. Everything happens on your device. PRIVATE BY DESIGN StackPeek requests only the minimal permissions needed to inspect the tab you choose to scan. It has no access to other sites, collects no personal data, and sends nothing anywhere. Free. Private. Unlimited.
