Code Diff Tool

The Code Diff Tool analyzes two code states from a Git workflow to expose exact changes at the file and line level. It provides both a side-by-side view and a unified patch suitable for review and patch generation. Conceptually, the tool treats each input as a text corpus and computes an edit script that transforms one state into the other. This enables precise identification of additions, deletions, and modifications across files. The backend focuses on textual differences, making it robust for projects of varying languages and sizes. It is particularly valuable for per-commit reviews, pre-merge checks, and historical audits. Unique value lies in its ability to produce clean, exportable patch data without relying on a UI, supporting automation and CI pipelines. Core features include file-level diff aggregation, per-file summaries, and export formats that align with Git workflows. Use cases span patch verification, merge conflict analysis, and change-tracking across releases.
The tool emphasizes deterministic diffs, naming-agnostic detection for renamed files, and optional normalization steps (line endings, trailing whitespace). It supports large repositories by streaming outputs and allowing selective diffing by file path or type. The approach stays language-agnostic and emphasizes reproducibility, which is essential for audits and code reviews. Its differentiator is a backend-first, scriptable diff service that can be integrated into CI, release tooling, or IDE extensions without relying on a graphical interface.
