LazyDiff is a terminal-based tool for reviewing Git code changes and GitHub pull requests without leaving the command line. A diff is a view of what changed between two versions of code, showing which lines were added, removed, or modified. LazyDiff gives developers a fast, keyboard-driven way to look through these changes instead of switching to a web browser or a full code editor. The tool runs directly in your terminal and shows diffs in either a unified view, where changes appear inline, or a split view, with old and new code side by side. You can browse changed files, jump between sections of a diff called hunks, search within the diff, and open pull request descriptions next to the files they touch. A pull request is a proposal to merge a set of code changes into a shared codebase. LazyDiff connects to GitHub so you can review pull requests straight from the terminal using a device-based login flow. It also detects semantic changes, powered by a companion library, meaning it understands the structure of languages like TypeScript, JavaScript, Python, Go, Rust, and Java, and can point out meaningful code changes rather than just raw text differences. LazyDiff suits developers who spend most of their time in the terminal and want their code review workflow to stay there. It handles local changes, staged changes, specific commits, and patch files, as well as GitHub pull requests, all through one consistent keyboard-driven interface. It is written in Rust and is currently in an early alpha stage, meaning it works but is still changing between releases.
