Random comment: Great to see this, Mcor technologies started in a little village in Ireland (the next village over from me). I called them once and asked if they had a bureau service. They put me directly on to one of the founders who was really friendly and knowledgeable (we started chatting about C++, OpenGL & slicing algorithms). I tried to get some of my best graduates (I lecture on OpenGL) to apply for their C++ jobs but most of my graduates have a Dublin/City-only view of the world and I never could convince them to interview for it.

I've been using Jetstrap and Divshot for 2 weeks on a small project. Of the two so far, I've found Divshot has more features and ease of use, yet Jetstrap is very good in its own right. I want to try Easel and I signed up, but the site seemed to be overwhelmed (by Show HN?) and it failed to load for me.

Surely we want competitors in this area, there's obviously a need for it and a number of tools competing on features and price can be good for consumers?

Thanks, I built Jetstrap :)

To answer the parent, Adobe technically does have a competitor in this space, though it's not focused on bootstrap and it's kind of complicated: http://html.adobe.com/edge/reflow/

As someone with a product in this space, I'm confident each of the current offerings listed above will diverge sufficiently in the future, specifically in their target audience. It's still so early though.

Sorry about your demo document on signup not loading. All should be fixed now.

And Max (yesimhuman) is right: it's pretty early, and we're all approaching the problem from different perspectives.

I think tons might be a slight exaggeration, if you restrict it to visual builders targeting Bootstrap, there's 2 publicly available alternatives. Both of those in BETA, all 3 look promising.
