Not the same. Disk files can be browsed via HTTP (HTTPS), so you can preview a local static site directly, without tools such as http-server, SimpleHTTPServer, etc.
Service worker file loader != HTTP server. You are intercepting requests which are usually fulfilled by HTTP, but you are not implementing or interacting with HTTP.

Even so, cool project.
If the files are served via HTTP I am missing it. A page which is fetched via HTTP and then accesses local files is not an HTTP server.
