About Code Difference Comparison Tool
Free online Code Difference Comparison Tool tool.
The Code Difference Comparison Tool places two snippets side by side and paints every change so you can see exactly what moved. Paste an old version on the left and the new one on the right, then read added lines in green, deletions in red and edits marked inline. It understands plain text and popular programming languages well enough to ignore formatting only churn, so reindenting a file does not bury the real change. Developers use it to review a pull request, verify a minified bundle, or confirm that a deployment did not alter a config file, while students compare two solutions before submitting an assignment. The Code Difference Comparison Tool runs in your browser, stores nothing, and is free without signup.

Frequently Asked Questions
Does the Code Difference Comparison Tool detect whitespace only changes?
It does. The comparison normalises indentation and line endings before matching, so reformatting a whole file does not appear as a wall of edits. You still see the differences that matter, such as renamed variables, changed conditions or deleted blocks, highlighted in colour. If you want the raw view, paste the text again and step through it line by line yourself.
