Rockmelt is a discontinued proprietary social mediaweb browser developed by Tim Howes and Eric Vishria based on the Google Chromium project, incorporating social media features such as Facebook chat, Twitter notifications and widgetised areas for other content providers such as YouTube and local newspapers. The Rockmelt web browser project was backed by Netscape founder Marc Andreessen. As of April 2013, Rockmelt discontinued its desktop web browser, replacing it with a collaborative project bringing together social elements from various sources. Rockmelt was created by Rockmelt, Inc., located in Mountain View, California. The final version, 2.2.0, was released on February 9, 2013. On August 2, 2013, Yahoo! acquired Rockmelt. Rockmelt apps and the website were shut down after August 31, 2013. Yahoo! plans to integrate Rockmelt’s technology throughout various products.
Rockmelt was positively received by Tom’s Guide, though they noticed that the RAM consumption was higher than in Chrome and Firefox. The browser's “Edges” were called “the three most prominent features of the RockMelt browser”. Notebook Review, while comparing Rockmelt to Flock, gave Rockmelt 4.5 stars out of 5, with the absence of extension support being the most noticeable issue with the browser. “The social networking integration is worlds better than Flock’s, and... there are at least some very useful features that RockMelt leverages. The news feed really is well done, and the Facebook handling is certainly better than Flock.” In a beta preview by Techcrunch, Rockmelt received mixed reviews mostly due to the browser using Chromium as its base, with a number of concerns whether the browser would find its audience. In a short review by PCWorld, Megan Geuss stressed the overall Facebook integration of the browsers, which would not work for every user, while also praising the performance of Rockmelt: “the fledgling browser works really quickly. It did an even better job than Chrome at processing HTML5”. A PCMech review of Rockmelt stressed how easy it was to share content via Rockmelt, and the browser received praises for the option to add additional feeds. “It is easier than manually going to Twitter or Facebook and is most certainly easier when managing feeds for the web sites you visit often. On top of that, it looks good.”
