Overview

See what any website is built with: CMS, frameworks, analytics, ad pixels, payments and chat. Runs fully on your device.

See what any website is built with. StackPeek detects the CMS, JavaScript frameworks, analytics tools, advertising pixels, payment processors and chat widgets in use on the page you are viewing. Handy for competitive research, for sales teams qualifying a prospect's stack, and for developers who want to know how a site was put together. The detection runs entirely on your device. StackPeek requests no host permissions and makes no network requests, so nothing about the sites you visit is ever transmitted.
