QFAQ

How does the comparison work? ＋

A longest-common-subsequence (LCS) diff at line level — the same approach behind git diff, so moved lines may show as remove + add pairs.

Is there a size limit? ＋

400 lines per side, keeping the comparison instant in every browser. Split very large files and compare in chunks.
