"Sublime Vergleich" is a free but powerful Diff and Merge tool for the text editor Sublime Text.

Sublime Vergleich offers following features:

Resources: You can diff various different ressources such as open files, files in project folders, contents of the clipboard, selections in open files or even multiple selections.

Side by Side diffing with synchroneous scrolling: You can easily see the compared files side by side with aligned rows. The scrolling is synchroneous (vertical and horizontal) which also helps while comparing files

Highlighting: Differing rows and blocks are highlighted and also displayed in the mini map.

Multiple diff sessions at a time: You can do many different comparisions at a time.
