Spiderpig is a website crawler designed to archive your own sites as flat HTML files. It works great for Wordpress or other dynamic sites, collapsing the site into a folder of HTML files, images and JS and CSS assets.



This will crawl, look for any links in <a> tags, and download all pages it finds to a folder called "". It will also find images, Javascript and CSS files that are linked from any HTML pages or even other CSS files. However any content loaded via Javascript won't be discovered by the script.

Why not just use wget --mirror?

Here is what Spiderpig does that Wget does not:

  • Ensures all filenames on disk are called "index.html" so that the URLs to the content don't change (aside from sometimes adding a trailing slash).
  • Ensures URLs such as /example and /example/1 do not conflict with each other, which they would if you were to write a file to disk named /example because then /example would be a filename and it would try to write a file named 1 into the folder /example which is a problem.
  • Spiderpig will parse CSS files looking for images referenced from the CSS file and download those images.
  • Keeps track of HTTP redirects it encounters, saving them to a file, so you can generate .htaccess or nginx rewrite rules to ensure all your existing redirects stay intact.
  • Query strings are ignored completely, since URLs with query strings can't be reliably served from disk. Also, cool URLs don't have query strings.
