Text diff, code diff and JSON diff
Text mode is useful for requirements, documentation and logs. Code mode preserves source formatting and lets you compare common programming languages. JSON & API mode parses both payloads and reports differences using paths such as $.data.user.status, making it suitable for regression testing and response validation.
