How big is your JavaScript?

Scan any site to see its bundle size, framework, hosting and third-party services, and how it compares with the rest of the web.

Notice:
When you provide a URL, we load this URL in a browser, look at the properties of the code we find there (size, versions, tool usage, compression headers, whether or not there is an SSL cert, and more), and then save those results along with the URL provided. We only load or save information that any user on the internet could see by loading a page and opening DevTools.
