What is a Text Diff?

A text diff (difference) tool compares two text files or strings and highlights the differences between them. It shows which lines were added (in green), which were removed (in red), and which remained unchanged. This is essential for code review, debugging, and tracking changes in documents.

Our tool uses a line-by-line comparison algorithm to provide clear, color-coded differences that are easy to understand and review.

Common Use Cases

Code Review: Compare different versions of code to see what changed
Debugging: Identify differences between working and broken code
Document Comparison: Track changes in text documents or contracts
Configuration Files: Compare config files to spot differences
Data Migration: Verify data before and after migration
Version Control: Review changes before committing to Git
API Responses: Compare API response changes over time
