Spot the differences, merge in seconds

Visit Kaleidoscope

Kaleidoscope is a file comparison and merge application for macOS that helps users identify differences in text files, images, and folders, and resolve merge conflicts. It integrates with Git for reviewing commits, browsing file history, and comparing branches.

Features include 3-Way Merge for resolving conflicts, a Changeset view for reviewing all changes between two commits with live working copy updates, character-level Text Compare with collapsible unchanged areas, pixel-level Image Compare with split/blink/drag modes and format and color profile details, and directory comparison with inline diffs and Quick Look. File History lets you browse and compare revisions of a file with commit context.

Kaleidoscope is available for macOS Sequoia (15.x) or later. A free 7-day trial is offered, with monthly and yearly subscription plans available.
