What is a Diff Viewer?
A Diff Viewer is a tool used to visualize the differences between two versions of text. Whether you're comparing code snippets, configuration files, or document drafts, a diff tool helps you spot exactly what was added, removed, or changed.
How it Works
Our tool uses a sophisticated line-by-line comparison algorithm. It carefully analyzes the structure of both inputs and generates a unified report:
- Green Highlights: Lines that exist in the second version but not the first (Additions).
- Red Highlights: Lines that exist in the first version but not the second (Deletions).
- Standard Text: Lines that are identical in both versions.
Total Privacy
Unlike many online comparison tools, we never upload your text to a server. The comparison logic runs entirely within your web browser using JavaScript, making it safe for comparing sensitive logs or private configuration files.
