Easy to export – choose the columns you want
Plenty of extraction options, including HTML elements with certain classes or IDs, regular expressions, or entire content in a number of formats (html, plain text, markdown)
Since v4.1 can download to a folder all images discovered
Configuration of various limits on the crawl and the output file size
