DiffPad
Compare text locally on your Mac.
DiffPad is a focused Mac app for comparing two pieces of text. Paste an original and a modified version — the comparison runs automatically. Review the differences in Side-by-Side, Inline, or Unified Diff views.
Features
- Side-by-side comparison with word-level highlight pills
- Inline diff view with dual-gutter line numbers
- Unified diff view with hunk headers
- Automatic live comparison as you type
- Ignore case, blank lines, and whitespace
- Copy unified diff or summary
- Built-in sample texts for quick testing
Privacy
DiffPad works entirely offline. It does not connect to the internet, does not use analytics, and does not upload your text. All comparison is performed locally on your Mac.
