FAQ
What is a diff?
A diff (from 'difference') is a comparison between two versions of text that shows exactly what was added, removed, or changed.
How is diff different from text compare?
They're the same thing. 'Diff' is the technical term (from the Unix diff command) while 'text compare' is the plain-English description.
Can I compare code files?
Yes — paste any code, config, JSON, or plain text. The tool highlights differences at the line level.
