What is a diff checker?
A diff checker compares two pieces of text and highlights the differences between them. It shows which lines have been added, removed, or remain unchanged. Diff tools are essential in software development for code reviews, debugging, and tracking changes.
How to use this tool
Paste the original text in the left panel and the modified text in the right panel, then click 'Compare'. Added lines are highlighted in green, removed lines in red, and unchanged lines have no highlight. Line numbers are shown for easy reference.
Common use cases
Comparing two versions of a file to see what changed, reviewing code changes before committing, checking configuration file differences between environments, and verifying that automated edits produced the expected results.
