Could you build this?
Partial While wrapping headless Chrome to capture HTML is easy, bundling a whole dynamic web application, assets, and custom runtime into a standalone, single self-executing binary requires non-trivial packaging and link rewrites.
What it would actually take: The architecture typically uses Go or Rust with embedded resources (e.g., via embed or rust-embed) wrapping a lightweight HTTP server and a headless browser driver. The difficult parts are deep web asset serialization (rewriting inline styles, JS fetches, service workers, and SPAs) to make them completely offline-functional, and cross-compiling everything into a zero-dependency static executable. Building it requires deep knowledge of web scraping mechanics, offline DOM serialization, and systems packaging.
