Pinegrow is a desktop app so it can be used offline. It is a visual web editor hence everyone can design a website using Pinegrow. There is no need to have programming knowledge for web designing. It is easy to use and has a rich library of elements.

One of the best web builders out there at a reasonable price. Real-time screen preview, no need for any other plugins whatsoever.Build complex pages with its drag-and-drop WYSIWYG interface without any coding knowledge.

It's the closest thing I've found to Dreamweaver, a desktop app that allows you to visually build HTML/CSS websites plus its multiplatform and has an option to purchase a perpetual license.
