I have developed more than 1000 websites using this framework and i think it's essential for running a web design business in an efficient manner.
Over the years i tried all the available themes in the market but i was always frustrated. They were very slow, loaded with tons of javascript very difficult to customize. Also weren't a good fit for my expanding business because they were very inefficient for making changes across the whole page. Fastway is optimized for:
It only weights 500KB. It has the minimum libraries needed for creating great websites. Also has built in a lot of functionality eliminating the need for extra plugins, which is essential for performance.
With multiple theme options i can manage to update things across all the site from a centralized command. Also it is really fast to create websites. I'm able to create a site in a couple of hours.
Provides customer ready dashboard so clients can perform the most important and urgent tasks making the tech support load more light. Also has every little thing every customer ask over the time.
It's very easy to make a fork of it and continue to add functionality. I have a local install of fastway and when i push changes to bitbucket its automatically updated in all the 200 sites i maintain.
