Text Diff

Available

Compare text, code and configuration line by line locally with readable hunks and unified output.

Runs locally. Your compared text never leaves this browser.

Compare two texts

Paste text, source code or configuration. Options change comparison keys but never rewrite the displayed source.

Ignore whitespace differencesIgnore case

Compare both sides to inspect changed lines.

Text Diff treats line order and textual content as meaningful instead of applying JSON-specific structural semantics.

Changed regions include nearby context and stable original/updated line numbers so code and configuration remain readable.

The diff engine runs entirely in this browser with explicit safety limits and no comparison payload sent to a Devary server.
