About Diff Checker
The Diff Checker compares two blocks of text or code and highlights exactly what changed between them. Additions are shown in green, deletions in red, and unchanged lines are displayed for context. This gives you an instant visual diff without needing a code editor or version control system.
Useful for spotting changes between two versions of a config file, comparing copied text for differences, reviewing what changed in a document revision, or understanding the delta between two API responses.
The comparison works line-by-line and shows a summary of how many lines were added, removed, and unchanged.
