AmSo Compare review
A broad Mac comparison tool for merging, syncing, and inspecting complex file changes.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AmSo Compare is a macOS application for comparing, merging, editing, and synchronizing folders and files. It is aimed at developers and other Mac users who need to inspect directory changes, reconcile text edits, compare binary files, or manage synchronization and mirroring tasks. Its scope extends beyond standard text diffs, with support for two-way, three-way, and N-way comparisons across folders and text files.
The standout strength is breadth. AmSo Compare supports automated and manual three-way and N-way merging, configurable comparison rules, filtering, and manual alignment. It also adds binary comparison with Hex editing, inline text and binary editing, image comparison, and structured JSON and XML comparison. Time Machine comparison and Git integration make it relevant to both source-control workflows and Mac backup review. This combination suits users who need several comparison modes in one application rather than a narrow text-only diff tool.
The published plan structure includes Monthly Subscription, Annual Subscription, and Full Purchase, with the last offering a permanent purchase option. AmSo Compare does not have an unrestricted free plan, so buyers should choose a plan based on whether they prefer recurring access or a permanent purchase. Mac users who need folder synchronization, multi-way merging, binary inspection, or structured-file comparison should find the feature coverage aligned with those tasks. Users seeking a simple, cross-platform, or free comparison utility should choose an alternative instead.
