Blue Crab for Android

11 things about Blue Crab

1. Blue Crab does not stray off the domain of the starting URL; in other words it won't try to download the whole web! You can restrict Blue Crab to a subset of the given website by specifying strings that restrict which URLs are grabbed.

2. 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.

3. Blue Crab is a versatile app that you use to download the contents of a website to your Mac, in whole or in part, and then search it.

4. 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.

5. Blue Crab has a special feature called the "Media Grabber" for easily downloading just the graphics, movies or PDFs on a website.

6. You also have the option of "flattening" the download directory, i.e. putting all the downloaded images into one folder, or preserving the folder structure on the server, just as when downloading a whole website.

7. Starting with a single webpage address Blue Crab begins traversing the site by following the links on the textual pages it finds, HTML, CSS, etc.

8. Blue Crab can search any file type supported by Spotlight, such as PDF or RTF, and provides convenient thumbnail previews.

9. Once you download a collection of files you can search them with the built in text search window, which displays found files hierarchically, matching their location on the website.

10. For example, you can choose to save only the images Blue Crab finds, or just the PDFs.

11. There is also a convenient "stay in folder" option in every grabber window which restricts the crawl to URLs whose path must begin with the path of the starting URL.
