I noticed that one time limit point apps that were released eons before the mac app store have suddenly all disappeared and 404 is now the response.

I might have missed the obvious but with the new site layout it is pretty bare so I am completely confused as to the state of limit point customers that purchased software now only available via MAS. We get coupons, etc.. or what? I prefer a DL from the developer but better MAS than nothing which is the drift I am getting but keeping fingers crossed is not the case.

So all of us that paid for the "bundle" of every app in existence now and to be released in the future by limit-point for one flat price is now in what state dev? Just very surprised for a developer I have always praised for their dedication to customer needs over developing multiple apps that are overall useful (like many MAS devs) - Hell the limit point utilities bundle + the other bigger apps is by far the best deal I have encountered, especially when those one trick utilities were the only way to get the task done and accessed via context menu before services.

I'm going to email developer directly, always good communication so if they don't post a response here first I will let others know what the deal is, if any (most likely me just being tired or dev not finished with a site upgrade etc... ) ...

I don't know. I was hopeful that this would be snappier than SiteSucker, but I'm seeing about a 4 times speed difference on the favor of SiteSucker really outperforming this app and being more "mac-like".

Additionally, I have to say that I'm not real keen on the features and the terminology used. It's not horrible, particularly for someone who knows what they're doing, but I could see someone getting lost pretty quickly on a few of the points and the initial delay of the tooltips.

I agree with some of the comments that this is the best web extractor. I tried them all on several occasions, and always came back to Blue Crab.

Blue Crab has proven to be the #1 software for grabbing up URL contents. The interface takes a bit of looking around, it is amazingly packed with features - but it's reliable and does exactly what it says it does, very fast.

Best of all, Limit Point Software has been VERY responsive to any and all questions.

If you're serious about web work, this software is the only way to go in this category, in my Humble Opinion...

This is a very poor quality app. It has a lame java interface. It's very unintuitive. The app itself is slow and buddy. It just got 180 404 errors trying to download totally random URLs from my site, url's that are not linked to anywhere on my site. Clearly there are some big bugs in this app's code. I'll give it two stars because after fighting with it, it did download all, or at least most of my website. But this app is about what you'd expect for a windows app. I would not recommend it, even if it was free. For $25, forget it!

Hello,

It is not a Windows app, it is a Mac app only,. It is not a Java interface. It is not written in Java. It is written in using standard Mac OS technology.

404 errors mean that the URLs it was trying to grab were not found. This sounds more like an issue with your web site than with Blue Crab.

if you could contact me by email, I would try to help you get better results.

Ciao

Hello again,

This is an addendum to my previous reply. I just want to point out that Blue Crab finds URLs in the pages it "crawls" using various methods. The objective of these methods is to produce the best reproduction of a website on your Mac so that you can view it offline.

Some of these methods will produce "candidate" URLs which may not really be URLs on your website. The only way to verify if it is a valid URL is to try and get it. If it is not a valid URL the server will reply with a "404 Not Found" reply.

What I could do is offer the option to not use this stronger technique of finding URLs, with the side effect that the download may not be as complete as it would be.

This said, I would also like to say this is the first time a user has given Blue Crab a bad rating for trying to generate a very accurate download of the site, despite the side effect that it may construct URls that do not exist in the process.

Ciao
Joe

Best app for this category in my opinion. Configurations are a bit unintuitive. I need to explore it more to really say that the ease of use, features, and stability are more bug related.

Hmm. My registered copy (ie not the demo) works fine under Snow Leopard. I have had no crashes and no lock-ups. I haven't come across a site that's too large to 'grab' yet and some downloads via Blue Crab have been in excess of 800MB (that usually includes videos, or trial apps, etc).

Sounds like something you guys should be taking up with the dev.

Don't rely on your msg being read here (although it might be for all I know), but email to joe@limit-point.com.

I just downloaded a copy and using it to download a graphics heavy site. The application quits after 5 min or so. It says this is a "fully functional demo" but is this "auto-quit" part of the demo? If so, how can I fully evaluate the program?

As I wrote this "review" I already had to restart the program 3 times so that "5 min" interval is getting shorter. I may start looking for an alternative. Too bad HTTrack is not available for the Mac.....

Blue Crab is a versatile and thorough program that you use to copy the contents of a Web site to your computer, in whole or in part, and then search or browse it offline.

Blue Crab lets you:
  • Conduct fast offline browsing and searching without an Internet connection.
  • Perform batch downloads of URL's
  • Create a snapshot of a website for historical archiving.
  • Batch download Web archives.
  • Collect specific types of resources such as images or email addresses.
  • Search current content more thoroughly than a search engine right on your own computer.
  • Check a site for broken links, or generate an HTML sitemap
  • Create full page images of URL's (JPEG, BMP, TIFF, PNG, PSD, etc.)
  • Perform "Google Image Search" batch downloads: download images found using an image query on Google.
With Blue Crab you can download all the content including HTML, PDF, 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 JPEG images Blue Crab finds, or just the PDF's.

Blue Crab has a special feature called the "Media Grabber" which you can use to easily download just the images (or movies) on a Web site Moreover, you can view a slide show of the images as they are downloaded. You also have the option of "flattening" the images, i.e. putting them all into one folder, or preserving the folder structure on the server (just as when downloading a complete Web site for offline viewing.)

Blue Crab is always gentle on the server, processing only one URL at a time. (You can even make it pause between successive downloads so as to not overwhelm the server.)

The demo version you download now is fully functionaly and runs for about ten days.

Major Features:
  • Unique URL extraction algorithms yield very complete downloads compared to other products of this type.
  • You can download Web sites either for offline browsing, via re-linking of URL's, or to create virtual copies of them on your hard drive, i.e. backup a Web site as-is.
  • Supports both HTTP, HTTPS protocols as well as server realms. Detailed Grabber window shows server HTTP header response fields.
  • Optionally display Web pages as they are crawled using either your own Web browser or Blue Crabs own Web window.
  • You can restrict a crawl to just the initial domain, or allow the program to "stray" into offsite URL's
  • Blue Crab can remap "dynamic" URL's which contain path and search arguments so that resulting disk files are navigable offline.
  • Image URL's into JPEG files (or any other graphic file type supported by Quicktime) to create complete pictures of Web pages not possible simply by taking a single screen shot yourself.
  • Blue Crab provides its URL imaging ability as a service menu item available from other applications.
  • URL's can be imaged into files, or onto the clipboard.
  • Built-in directory search displays found files as a hierarchical list, with double-clickable entries.
  • A "batch window" enables you to download your own list of files. Simply drag and drop URL's into the batch window, or import them from an HTML file , or text file.
  • Grabbing in "images-only" mode just downloads image files, optionally "flattening" the results (i.e. putting all images into one folder.)
  • Reusable configuration settings control what is grabbed, saved or crawled:
  • Filter by size, date, file type or even content
  • Filter by filename, extension or path
  • Bookmarks window for storing frequently crawled Web sites
  • Supports form submissions to enable you to begin a crawl from a login page.
  • Supports cookies for more accurate downloads.
  • Generate site maps that consist of a hierarchical display of URL's Such maps can be optionally filtered by extension.
  • Find email addresses.
  • Customizable user-agent (spoofing) enables you to download Web sites which are platform specific.
  • Optionally receive email notifications of Blue Crab's progress during a lengthy crawl.
  • Dock badging provides visual feedback or progress when the program is in the background.
  • Google image search and download in batch.
Updates are free.
