Protoship Codegen is a code generator for designers and front-end programmers that creates HTML, SASS, and React components from a Sketch design. You will be able to go from a design to a working application in a matter of hours instead of having to go through the tedium of writing HTML and CSS manually.
Protoship Teleport can convert any website into a Sketch mockup instantly. It lets you reuse layouts and design elements from all over the web without having to start from scratch.
Teleport beta is available as a public release. Get it here.
