MergeDock - Native diff & merge for files and folders on macOS

MergeDock is a native macOS diff & merge tool for comparing text, folders, images, and binary files. Edit files side by side, perform 3-way merges, integrate with Git, and work with very large files. Built for developers who want a fast, focused, Mac-native comparison workflow.
