RockMelt 0.9

RockMelt is a proprietary social media web browser developed by Tim Howes and Eric Vishria. The project is backed by Netscape founder Marc Andreessen.

RockMelt integrates a unique technique for surfing the web that focuses on Google Search and Social Media, in particular Facebook and Twitter. The browser launched in private beta on November 8, 2010; in order to download it, users are required to connect their Facebook account to the website to receive an invitation email. RockMelt supports Windows and Mac OS X platforms.
RockMelt is based on Google's open-source project Chromium, a cross-platform family of browsers (available for Windows, Mac and Linux) that use the open-source web layout engine WebKit—jointly built by Apple, Google and the open-source community—but have the JavaScript engine replaced by Google's own V8, also open-source. Version 3 of Flock, an older social web browser project and therefore a primary competitor to Rockmelt, is also based on Chromium.
