Differences between two texts

Differences between two texts: mode lines, words or chars; the added, removed and unchanged parts with counts, a similarity ratio (2 x unchanged / both texts' units), and a unified diff for lines. Body { a, b, mode }: lines and words up to 50 KB each, chars up to 20 KB each (capped for the Worker's CPU budget). Pure code using the diff package (BSD-3-Clause).

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
