Really well done and feature-rich. Every web developer has thought about a product like this at some point. However, I don't understand who you're targeting: It's an incredibly feature-rich product, but no clear value proposition. Are you targeting backend developers that can't write HTML/CSS? Are you targeting HTML/CSS-devs that need a better IDE? Are you targeting website optimizers?
Your product seems like a combination of IDE, web-based WYSIYWIG (à la Weebly or Unbounce), SEO/Optimization (Optimizely or VWO), and Chrome Developer Tools. The integration is great from a technical perspective, but I don't see why I as a Web Dev should switch my entire tool chain to your service. The USP is kind of missing.
(I'm also from Germany, and the rendering is kind of slow, as hxseven has mentioned. Not sure if due to connection or client-side JS.)
