Check out this feature comparison table.
What content can Content Grabber extract?
Content Grabber can extract pretty much any content (images, text, PDF, documents, videos, etc) that you can manually navigate to online.
How should the Content Grabber server license be used?
The Server Edition is for use on test and production servers to manage and run web scraping agents. While you can maintain your agents using the Server Edition, it does not facilitate the creation of new agents. People often want a separate production server to their development environment. It is a cheaper alternative than buying a full license for production.
Can I upgrade from a Professional Edition to a Premium Edition license?
Yes, you can upgrade from a Professional Content Grabber License to a Premium License as long as your maintenance agreement is valid. The upgrade price is US $1500. Please note that any web scraping agents created in the Professional Edition, when opened in the Premium Edition will only be able to utilize the feature set of the Professional Edition (e.g. the API features of the Premium version won’t be accessible to this agent).
How does Content Grabber’s maintenance and support agreement work?
When you buy a Content Grabber license, it includes 6 months maintenance and support at no additional cost. This will entitle you to continual software updates and support during this period. At the end of the 6 month period, you can renew you maintenance and support agreement for another 12 months from the Content Grabber support database.

Is there a project migration process / utility from Visual Web Ripper to Content Grabber? (Can I import my old project into Content Grabber?)
Yes – Content Grabber includes a migration feature for Visual Web Ripper projects. Note however, that some manual work will likely be required for complex projects, particularly those that utilize the API or custom scripts.
Are there features in Visual Web Ripper that are not included in Content Grabber? (Am I losing any functionality when migrating?)
The features in Visual Web Ripper also are available in Content Grabber plus many more. Many features will work differently but in a superior way.
The only exception is the API. VWR has a completely open, and mostly undocumented, API. Content Grabber has a documented, but limited API. In our opinion the Content Grabber API is much more useful in most situations. You may however find things you can do with the Visual Web Ripper API which you will not be able to do in the Content Grabber’s API.
Is there a purchase discount to migrate to Content Grabber?
Yes. If you have active maintenance for a Visual Web Ripper license, you will get a $US 100 discount. You also get to keep your Visual Web Ripper license. Note: You cannot combine multiple Visual Web Ripper licenses (or seats) into one big discount for a single Content Grabber license.
