Turn Websites into Desktop Apps
"Web applications are becoming more and more like desktop applications but running each of these web apps in a separate tab in your browser can be a real pain.
WebCatalog lets you turn any web apps into desktop apps (a.k.a. site-specific browsers). Now, you can launch your favorite apps quickly in self-contained, distraction-free windows with many additional features to enhance your workflows.
Even better, with sandboxing, it also protects you from cross-website trackers and preserving your privacy."
Note: WebCatalog has been open-source, but moved to a closed source code base.
