-A google-chrome extension to compare the same page accross multiple sites (js)
+I found myself having to compare pages quite often when upgrading legacy web applications.  
+Often the urls were very similar, but the hostname changed or one extra componenet was added.  
+In order to speed up copy-pasting and editing, 
+I made a simple javascript chrome extension to do that work in one click.  
+
+The example in the README uses stack exchange sites, since they mostly follow the same url
+pattern, but have different host names.
