Currently the only supported browser engine is Internet Explorer. Support for Chromium and Gecko will be added in a future update.

WebCopy now includes limited support for crawling websites that are constructed using JavaScript. An external browser engine is used to crawl the website, along with existing WebCopy spider support.


This feature is currently experimental and not feature complete

  • The only browser engine currently supported is Internet Explorer
  • Website crawling may be substantially slower
  • Custom user agents are not supported
  • Websites will be able to track you and use system cookies
  • Malicious script served by compromised servers or rogue adverts will execute
  • The content that WebCopy downloads may be different if the website uses browser sniffing to reduce functionality for IE users

Unsupported features

Interactive options are not supported, for example clicking nodes in a dynamic tree or scrolling a page which uses infinite scroll. There are no plans to add support to allow for user interactions to be dynamically performed.

Note that this still does not provide privileged access to a webserver, it is still not possible to download the raw source code of a website or its back-end databases unless the website specifically allows for this.

Future feature support

As noted, this is currently experimental. Future versions of WebCopy will include options for choosing between specific versions of Chromium or Gecko.

Enabling JavaScript support

To crawl websites with support for JavaScript execution enabled

  1. From the Project Properties dialogue, select the Web Browser option group.
  2. Check the Use web browse option
