What it is

Diffinity is a free Windows utility for comparing and merging text files and folders. It shows line-level differences, highlights changed characters or words, and marks added, removed, and changed lines. A thumbnail view summarizes differences, while search can highlight every instance of a selected word. The maker emphasizes readable source-code comparisons, including improved diffing for C-style code and XML. Editing tools include syntax highlighting, customizable tabs, manual alignment markers, and inline differences that update while typing. Diffinity supports Unicode, detects encoding automatically, and warns when compared files use different encodings. It integrates with Windows Explorer, can run from an external device, and accepts file or folder paths with command-line options, including a folder-diff view. Documentation covers configuration with Git and Perforce Helix P4V. The license allows free personal and commercial use and redistribution of unmodified copies, while prohibiting modification and reverse engineering. Listed release 0.9.6, dated 2026-09-16, requires .NET 8.0.
