Smippo Documentation
S.M.I.P.P.O. (Structured Mirroring of Internet Pages and Public Objects) is a modern website copier that captures websites exactly as they appear in your browser. Unlike traditional crawlers that nibble at raw HTML, Smippo vacuums up everything—rendering pages in a real browser, intercepting all network requests, and creating structured offline mirrors with complete fidelity.
Why Smippo?
Traditional website copiers were built for a simpler web—static HTML served from servers. Today's websites are JavaScript-powered applications that fetch data dynamically, render content client-side, and use modern CSS techniques. Traditional tools simply can't capture these sites properly.
Smippo launches a real browser, navigates to pages, waits for JavaScript to execute, captures all network requests, and saves the fully-rendered result. You get the page exactly as you see it in your browser.
Key Features

Complete Fidelity
Captures pages exactly as rendered, including CSS-in-JS, dynamic content, lazy-loaded images, and web fonts.
Smart Filtering
