About

Compare two texts line-by-line to find additions, removals, and changes. Ideal for config diffs, release notes, incident timelines, and quick reviews. Runs locally in your browser.

Use cases

  • Compare two versions of a config file before deploying.
  • Review changes between two API responses saved from logs.
  • Spot differences between generated outputs and expected results.

Common pitfalls

  • Line ending differences (LF vs CRLF) can cause noisy diffs—normalize if needed.
  • If ordering changes, a line diff can look huge; sort or format inputs first for clearer comparisons.

Examples

Input

left=hello\nright=hello world

Output

+ world

FAQ

Can it ignore whitespace or case?

Not yet. For now, normalize your input (trim/format) before diffing, or use a specialized diff tool.

Do you upload my text?

No. Diffing is computed locally in your browser.

Why does it show many changes?

Line-based diffs can look noisy if lines shift. Consider sorting or formatting inputs first.

Is this suitable for large files?

Large inputs depend on your browser performance. If it’s slow, use a CLI diff tool.

Limitations

  • This is a simple line-based diff (not a full Git diff).
  • No built-in ignore-whitespace or ignore-case modes.
