The three most common workflows for comparing code, config, and copy line by line.
Confirm you are comparing the same level of text
Line comparison assumes both sides have consistent structure. Check line endings and leading or trailing spaces before pasting to avoid meaningless differences.
Paste config content as-is rather than formatting it first, since formatting noise can hide real changes.
Focus on additions and deletions, not whole-block changes
The added and removed lines matter most. Look at those two groups first and treat unchanged lines as context.
If an entire block is marked as changed, the content probably did not change. Indentation or line endings likely did.
Export the result promptly
Sharing the prefixed diff result with teammates is easier to review than a screenshot.
Both inputs and results are handled locally in the browser, so it is safe to paste sensitive content.
