Beyond Compare vs SourceGear DiffMerge

Beyond Compare compares folders, text files, images, and tables so users can inspect differences and merge changes. Folder comparisons can include recursive subfolders and filters based on modified time, size, filename case, or file content. Text tools provide syntax highlighting, inline editing, and options to ignore whitespace or comments; Pro adds two-way and three-way text merge. Other supported data includes CSV, tab-delimited files, HTML tables, Excel worksheets, binary files, images, and audio tag data. Folder Sync can reconcile data with disks, FTP servers, and zip files, and command-line scripts can run scheduled syncs. Pro also includes secure FTP connections, remote Subversion repositories, and cloud storage options such as WebDAV, Amazon S3, Dropbox, and OneDrive. It runs on Linux, macOS, and Windows. The license is a one-time purchase, with Standard Edition at $35, paid once per user and Pro Edition at $70, paid once per user. Free evaluation is available, but continued use requires a license.

SourceGear DiffMerge is a free desktop application for visually comparing and merging files and folders on Linux, macOS, and Windows. Its Diff feature displays changes between two files, highlights differences within lines, and supports editing. Merge compares three files and can combine changes automatically when it considers that safe. Folder Diff compares two folders side by side and classifies files as identical, equivalent, different, or present in only one folder. Rulesets and options let users adjust its appearance and behavior, and it can import files in a wide range of character encodings. A command-line interface compares files and can write differences in unified or traditional formats. The manual documents integrations with Git, Mercurial, TortoiseSVN, Microsoft TFS, and Microsoft VSS 2005. Windows Explorer integration adds context-menu actions for selected files or folders. The download page lists version 4.2 builds for Windows, MacOS 10.6+, Ubuntu 12.04+, and Fedora 17+. SourceGear support stated in February 2026 that it was no longer accepting registrations and was moving DiffMerge toward an open-source project.
