Beyond Compare

Beyond Compare is a data comparison utility. Aside from comparing files, the program is capable of doing side-by-side comparison of directories, FTP and SFTP directories, Dropbox directories, Amazon S3 directories, and archives. It is available for Windows, Mac OS, and Linux operating systems. A strength of Beyond Compare is that it can be configured as difftool and mergetool of version control systems, such as git. .
