This is a file comparison plugin for both Sublime 2 and 3.
Enjoy!
Please install Sublime Package Control first. Then inside Package Control: Install Package, type Diffy and then click to confirm.
After installing the plugin, set the layout to be 2 columns via View -> Layout -> Columns: 2. And make sure you have files (or temporary files pasted from clipboard) opened side by side.
