Codiff is a newly released local diff viewer for macOS that allows developers to review staged and unstaged Git changes efficiently. It includes features like inline comments, Markdown export, and LLM-guided walkthroughs. The tool aims to improve local code review workflows with a native app experience.
Developers can now use Codiff, a new native desktop application for macOS, to review Git changes locally before committing, offering a fast and minimal interface with advanced review features.
Codiff is a local Git diff viewer designed for macOS, released in version 0.1.0 on May 17, 2023. It enables users to review both staged and unstaged changes efficiently within a native app environment, emphasizing speed and visual clarity. The application supports inline comments on changed lines, allowing for detailed review notes, and provides an option to export the review as Markdown, preserving diff context for future reference.
One of its notable features is the command-line helper, ‘codiff -w’, which generates walkthroughs using large language models (LLMs). This feature aims to assist developers in understanding code changes more comprehensively. The app can be downloaded for macOS from its release page, and users can enable the ‘codiff’ command-line tool via a dedicated installation process within the app.
Why It Matters
This development matters because it introduces a native, streamlined tool for local code review, potentially improving developer productivity and review accuracy. Unlike web-based or cloud solutions, Codiff offers a privacy-focused, fast, and integrated experience for Mac users, which could influence workflows and tool preferences in development teams.

Background
While many code review tools focus on remote or cloud-based solutions, local diff viewers are less common but valued for privacy and speed. Prior to Codiff, developers often relied on command-line tools or integrated IDE features. The release aligns with a broader trend of creating lightweight, native applications that enhance developer workflows without relying on external services.
“Our goal was to create a fast, beautiful, minimal native app for reviewing local Git changes that integrates seamlessly into developers’ workflows.”
