Compare Code Online, Line by Line
BHR Tools Code Difference Checker helps you compare an original code version with an updated version directly in your browser. It highlights added, removed and modified code so you can review changes without manually checking every line.
How to use the Code Difference Checker
- Paste the original code into the Original / Old Code editor.
- Paste the revised code into the New / Updated Code editor.
- Select Compare Code to generate the difference result.
- Use Previous Change, Next Change and the line navigation controls to review individual change blocks.
What the comparison shows
The result separates additions, removals and modified blocks, with line references for both versions. You can focus on changed blocks or review the full line-by-line comparison, then copy the result when needed.
Private, browser-based comparison
The comparison runs in your browser, so the code entered into this tool is not sent to a BHR Tools server for processing.
