Xvast is a Google Chrome based web browser with no plugins, HTML5 features, PDF capabilities, and more.Everything about Xvast will be familiar to Google Chrome users. It is fast, as promised. It promises no ads, but we did see our ads and no settings for it. There are no plugins and the browser doesn't try and load a custom start page as so many other do. PDF viewing works fine as well.The browser also supports DRM protection, which also might be one of the reasons for the browsers existence as it appears they have a product called DRM-X, which isn't cheap. DRM-X is designed to allow the delivery of DRM-protected media through the browser without the use of plugins such as Flash or Silverlight. We didn't notice any settings for this either so if it works for free within the browser without any nags, that's ok. Otherwise, that app is a subscription model starting at a ridiculous eighty dollars a month.There are plenty of Google Chrome based web browser and if you're looking for speed and stability, Xvast should do it for you. We'd like to see a portable version.
