Maybe a local http server that provides access to a selenium session as
   if it is non-js html?

   I found [1]https://github.com/alexandernst/headless_browser
Headless browser based on WebKit
================

This tool will help you make your AJAX applications crawlable.

Webpages based on JavaScript MVC libraries can't be positioned
by default because search engines can't run (yet) all the
JavaSript code that your page needs to execute in order to *show*
anything. That's why you need a headless browser that will fetch
the page, run the JavaSript and output the resulting HTML to the
crawler, which will then be able to index your page.

   from [2]https://github.com/dhamaniasad/HeadlessBrowsers , a list which
   attempts to enumerate all headless browsers and apis.
   I'm on mobile and haven't tried it.
   I'm interested if anyone finds a free-beer ecommerce scraping solution
   or other tools for connecting the cli to the web.
