Text Diff

Compare two texts or files side by side or as a unified diff, with changed words or characters highlighted, ignoring whitespace or case if you like.

Paste two versions of a config file, script, log or document to see exactly what changed: lines added, removed and modified, with the changed words or characters highlighted inside each line. The unified view is the same format as diff -u and git diff, so you can save it as a .patch file or paste it into a ticket.
