Thanks a lot!
The basic idea was to help developers like myself who are not very great with front-end development but have a good back-end knowledge. Once I started developing it (and picked up front-end development along the way), I realised that the even developers who have fair knowledge of the front-end part can really utilise a browser based tool for visual CSS development since a lot of us use browser tools like Firebug and Chrome developer tools which tend to get quite limited.
So yeah, that's how the idea evolved and I started creating a visual editing tool that not only helps developers with visual development but also provides a more extensive browser based coding IDE.
Browser plays an integral role in most of the web development cycle and so if we can combine the development and testing process and create a more streamlined Test Driven Development flow, it save a huge amount of time.. especially when it comes to responsive web development..
The way I envision it is to create a full stack development IDE inside the browser itself; so the only developer tool anyone would need is just a browser.. HTML/CSS/Javascript/Database+Server-Side Programming.
So yeah, to come back to the question...I am targeting mostly developers (majorly freelancers) right now.. who have a lot of work load and can actually benefit by saving a lot of time by using StackHive..
After that I think there is a great opportunity to bring on Designers onboard as well and create the full web development ecosystem inside the browser :)
(For the slow rendering, I made a temporary fix for now.. sorry about that.. should be able to get it in the groove in a few hours!)
