Text Diff

About Text Diff

Text Diff compares two text blocks side-by-side with line-level and character-level highlighting. It makes it immediately clear what changed between two versions of any text — code, configuration, documentation, or prose.

Common uses include comparing two versions of a SQL migration script, reviewing changes to a config file, spotting differences in API responses from two environments, or verifying that a copy-edit preserved the intended meaning of a paragraph. Character-level highlighting catches subtle changes like extra spaces or swapped characters.

Comparison runs entirely in your browser — neither text block is transmitted to a server.
