Limitations

This is a line-based LCS diff, not semantic code analysis, and it does not highlight word-level changes inside a line.

FAQ

Is the comparison character- or line-based?

v1.1 uses line-based comparison for lists, settings, and text versions.

How much can it compare?

Each side is limited to roughly 800 lines to avoid freezing the page.
