Code Diff Checker for Code Reviews
Quick Answer: Paste the original and modified code to see changes highlighted with syntax coloring. Green lines are additions, red lines are deletions. The side-by-side view mimics the GitHub PR review experience for quick code review outside of Git.
FAQ
When would I use this instead of GitHub diffs?
For comparing code snippets from Slack, documentation, or different files. Also useful when comparing code from different repositories or branches that are not in the same Git history.
Does it support syntax highlighting?
Yes. The diff view includes syntax highlighting for common languages: JavaScript, TypeScript, Python, Go, Rust, Java, HTML, CSS, and more.
