Blue Crab is a versatile app that you use to download the contents of a website to your Mac, in whole or in part. With Blue Crab you can:
• Conduct fast offline browsing and searching of a website.
• Create a snapshot of a website for historical archiving.
• Collect specific types of resources such as images or email addresses.
• Search current content more thoroughly than a search engine right on your Mac.
• Check a website for broken links, or generate a site map.
• Download groups of URL links at one time.
With Blue Crab you can download all the content including HTML, PDFs, graphics, video, file archives, etc., or use selective filtering to restrict downloads to specific kinds of files. For example, you can choose to save only the images Blue Crab finds, or just the PDFs. Blue Crab also supports "batch downloading" where you can collect a bunch of URLs, say by dragging them out of a browser window into Blue Crab, and then download them all at once.
