View every capabilityAvailable on the Mac App Store and Microsoft Store. Free desktop use lets you try every comparison engine for files up to 5 MiB per side and 10 new comparison sessions per local day; collection previews show the first 100 items, binary comparisons the first 100 byte differences, and PDF previews the first 3 pages. Plain text, JSON, and Jupyter notebook comparison are complete, and opening files from Finder or File Explorer, diffanything:// links, and AppleScript are free. The free CLI supports text, JSON, and notebooks, and the command-line helper that brings the CLI to the Mac App Store version is a free download that uses the Pro purchase made in the app. A one-time Pro purchase removes the preview and session limits and unlocks larger sources within technical limits, saved profiles and history, saving folder snapshots, report export and printing, JSON Patch export, applying patches, three-way merge and conflict resolution, the Git merge driver and merge tool, folder synchronization, batch manifests, every CLI mode, and, on Windows, trusted preprocessors.
