Beyond Compare
Beyond Compare is desktop software for comparing and synchronizing files and folders on Windows, macOS, and Linux. It can compare folders, text files, images, and tables, then combine changes from two versions into one output. Folder Sync helps reconcile differences and copy data to or from disks, FTP servers, and ZIP files. Repetitive comparison or synchronization work can be automated with its scripting language and command-line interface. Pro adds text and folder merging, source-control commands, SFTP and FTPS, registry comparison, and integrations for WebDAV, Dropbox, OneDrive, Amazon S3, and Subversion. The download includes Standard and Pro functionality for a 30-day trial; continued use requires a license. Per-user perpetual licenses for one to four users cost $35 as a one-time purchase for Standard and $70, paid once for Pro. Site and enterprise options are also listed. The maker says compared data is not sent externally unless a networked repository is used. Licenses are not available as floating, concurrent, or server licenses.
