Compare Suite vs Meld

Compare Suite is a Windows file comparison tool for office professionals, developers, and webmasters. It compares Word, Excel, PowerPoint, PDF, web pages, and plain text, and can produce reports with comments attached to differences. Spreadsheet comparisons show absolute or percentage changes in numbers and date differences in days. PDF comparison extracts text, so scanned PDFs need OCR before their text can be compared. The software can compare and synchronize local or remote folders, compare files over FTP, and inspect ZIP or RAR archives without unpacking them. Command-line automation and integrations with third-party document management systems and tools are also listed. The maker says processing happens locally and opened files remain on the PC. The free Light plan covers basic file comparison; paid one-time licenses are $70, paid once for Standard and $140, paid once for Professional. A fully functional 30-day evaluation is available. Windows 10 or Windows 7 is listed as a minimum requirement; Word and Excel comparisons require Microsoft Word and Excel, and Office 365 is not supported.

Meld is a free, open-source desktop tool for comparing files, directories and version-controlled projects. It provides two-way and three-way comparisons, with live updates while files are edited and merged. Three-way merge assistance handles conflicts and shows the base version. Folder comparisons identify missing or modified files, let users open deeper file comparisons, and can ignore selected files or folders. Meld supports Git, Mercurial, Bazaar and Subversion, including use with tools such as git mergetool. It is packaged for most Linux and Unix distributions and is available through Flathub. Windows users download an installer; automatic updates and portable installations are not supported. Meld is not yet supported on macOS, although the site points to semi-official builds and package-manager options. The project is licensed under GPLv2 or later, except as noted. The listed Meld plan costs nothing, and the stable release shown is 3.24.0.
