Difference between CMS builder and Power CMS?

Is the difference between these two products that PowerCMS is a single license? I was looking for a comparison chart since they seem so similar to me. But that's the biggest thing I notice.

Do either have a rollback ability, in case the client messes up the edit?

Thanks.

CMS Builder definitely does and I am fairly sure that Power CMS does as well

One big difference is that powerCMS is a single license... it is also not a dreamweaver extension like CMS Builder.

CMS Builder is for working within Dreamweaver. It shows you your content at design time in dreamweaver and allows you to create content by highlighting it in your dreamweaver page and adding it directly to your powerCMS database without using a browser.

What doesn't make sense to me at the moment is why does this version not require multiple licenses but PowerCMS does? Once the CMS Builder is used doesn't the client login just like they would as if you created a backend through PowerCMS? DOn't both offer the same options once the build is complete. I wish there was a better comparison video to show why I would want one over the other. Right now I can't decide whether I need this or not.

Neither CMS Builder nor Site Sculptor require multiple licenses. The differentiation we make is between a solution and an extension. All of our Dreamweaver extensions have developer licenses, but require you to install an .mxp into dreamweaver and use dreamweaver in order to work. Solutions are pre-built applications that don't require Dreamweaver.

They do offer the same options once you have completed building a site, but the client experience isn't what we base the licensing terms on, it is the developer experience.

You would only need CMS builder if you were developing multiple CMS web sites and/or value the ability as a developer to view your data from within dreamweaver and design your cms content from within dreamweaver rather than using the online editor. Your end user experience should be identical.

Does the new PowerCMS 2.1.1 address the issue of allowing/enabling clients to update/edit menus on the site (as WebYep by Objective Development does)?
This is the only reason I have never used this cms-as it needed a developer/designer level of understanding to edit a navigation menu.

The only updates in the new powercms release are bug fixes and updates to use the newest html editor version.
