Hi,

If you're familiar with sites like Weebly and Unbounce, you'll know that they allow users to login and build web pages and sites.

I wanted to confirm the technology they use for this functionality of letting users build pages and sites (I presume its built in house and combination of javascript and server-side programming language)?

and if there is third party software plugins available which will enable my users with similar functionality?

Hope this makes sense.

Thanks.
