Web developers are pretty lazy theese days to draw design from scratch in Photoshop and produce markup and CSS. It's much easier to use one of those prototyp apps with popular UI frameworks like Twitter Bootstrap or Foundation. Divshot, Easel, JetStrap are good to start with.

• Easel.lo

Easel was borne out of our frustration with the current state of design tools. Development tools have improved as the web has matured but design tools haven't. We started Easel because we want to create better design tools for the Web.

• Divshot

Divshot is an interface builder for web apps that exports clean, semantic code. The same code a professional would use in the real world. We believe there's a better way to design web apps beyond photo editors, mockup tools and repetitive code.

• Jetstrap

Jetstrap is a 100% web-based interface building tool for Twitter Bootstrap. No software to download, just log in and build. Your work is accessible from anywhere.

• Layoutlt

Drag-and-drop the same Bootstrap components to your own design. Easy to integrate with any programming language, you just download the HTML and start coding the design into it. Professional and validated HTML where you can replace with your own variables, loops or anything you need!
