How it works
How it works
- Compares files line‑by‑line at the same indexes; unchanged lines are copied, others are shown as deletions (−) and insertions (+).
- Not an LCS/ Myers diff: moved blocks and inline changes are not detected; it’s fast and simple for small texts.
- Normalize line endings first if comparing content from different OSes (CRLF vs LF).
Privacy & Security
No server calls; comparison done locally.
Accuracy, Limits & Tips
Not a full LCS diff; does not detect moved blocks or inline changes.
Examples
- Paste old config left, new config right, click Diff.
- See added and removed lines.
