This is about as good as a site can get to offer just the Bible.
Literal Word exists to promote the Word of God and not much else. No ads. No frames. No logging in. No distractions. Simply the Word. We believe that the Bible contains the most important information that anyone could ever come across and that accessing it should be as easy as possible. This belief has driven every decision we've made designing Literal Word. World class literal translations (NASB and ESV) were selected for their faithfulness to the original languages. Each page of Scripture is clean, customizable, and shareable with a single click, allowing the reader to focus exclusively on the God-breathed content. Searches are simple but powerful, utilizing a unique visual interface for organizing results with surgical precision. It all comes down to the idea that a minimalist approach to an online Bible maximizes attention to the Word of God.
I'd love to see the NET Bible added here. I suggested it to them, but never heard back. But the format they offer is about perfect.
