Free OS X utility to scrape web sites?
You have two options:
You can use the wget
command-line utility like so:
wget -rl 10
Replace the 10
with the number of levels you would like to recurse down into.
Or, you can use SiteSucker. A GUI application that recursively downloads websites. You can also specify how far down to recurse with SiteSucker.
