kdiff3
kdiff3 is a free, open-source file and folder diff/merge tool from the KDE project. It compares and merges text files, showing differences in a side-by-side or three-way view, and is widely used by developers for code review, version control integration (Git, Mercurial, SVN), and resolving merge conflicts. It supports syntax highlighting, line-by-line navigation, and can be configured as an external merge or diff tool in Git and other version control systems. kdiff3 runs on Windows, macOS, and Linux.
AI Recommendation
1 suggestionA native Apple Silicon (arm64) build of kdiff3 has been available since version 1.11.2, released in June 2024, and is available directly from the KDE project's download page. If you are running an older Intel-only build under Rosetta, download the latest macOS version from download.kde.org/stable/kdiff3 — the KDE mirrors automatically serve the native arm64 DMG on Apple Silicon Macs. After installing, your existing Git and merge tool configurations will continue to work without any changes. Expect better performance and lower CPU usage compared to the Rosetta-emulated version. Since more than two years remain until macOS 28 arrives in September 2028, there is no immediate urgency, but updating to the native build will give you noticeably snappier performance today.
