Riffle

Riffle is a fast, native Mac app for comparing files and folders, reviewing code changes, and resolving merge conflicts. Clear visual diffs and an editable three-way merge help you see what changed and get it right. It integrates with Git, popular Git clients, and AI coding agents, so you can review an agent’s edits separately from your own work.

Key features

• Three-way merge — Step through changes and conflicts, choose a side, and edit the result directly.
• Folder comparison — Compare directories with support for .gitignore and custom exclusions.
• AI agent review — Review a coding agent’s edits separately from your own unfinished work.
• Git integration — Open comparisons and merges from Git, popular Git clients, or the command line.

• Powerful search — Find text across comparison panes or every changed file in a review, with regex support.
