Preguntas frecuentes
Is my text sent to a server?
No. Everything runs locally in your browser — your text is never uploaded, stored or logged.
What kind of diff is this?
A line-based diff using a longest-common-subsequence algorithm — simple, readable and dependency-free. It is not a word-level or character-level diff.
Is there a size limit?
Very large inputs are skipped with a notice, since a line-by-line diff grows with the product of both line counts.
Is it really free?
Yes — free, with no signup and no limits.
