Macaw looks very impressive. As the narrator mentions in this twenty minute video demo, you can get into dangerous territory when a web design tool tries to also be a full WYSIWYG code generator at the same time (maybe I’m just picky, but as cool as Sketch is as a program, it’s HTML/CSS export options are not as great as I’d like.) Macaw seems to take a really balanced approach: fundamentally a design tool, but with most of its settings and tools rooted in HTML/CSS fundamentals.
Perhaps most importantly, while the app is native, it apparently renders all of its content in actual HTML. No more gradients, font styles and other “Photoshop only” actions that look very different once they actually get rendered in browser code.
I’m keeping my eye closely on this one.
