When to use

Examples
How it works
Line split → LCS/Myers-style diff → render. Optional ignore-whitespace.
Common pitfalls
- Word-wrap and ignore-space change what counts as a change.
- Binary files don’t belong here.
- Huge files may lag in-browser.
How this differs
Two-document compare. Regex Tester finds patterns in one text. JSON tools don’t diff trees unless you paste both sides.
