DiffDuo is a free online diff checker that compares two texts, files or code snippets directly in your browser. It shows removed lines in red, added lines in green and highlights the exact words that changed, in either a side-by-side split view or a git diff-style unified view.
Read changes in two columns side by side, or switch to a single-column unified diff in the same format as git diff and patch files.
Darker highlights mark the exact words and characters that changed inside a modified line, not just the lines that differ.
The comparison runs entirely in your browser, so confidential code, contracts and config files never leave your device.
Ignore whitespace, indentation and capitalisation differences, and control how much unchanged context is shown around each change.
