Advanced diff visualization with syntax highlighting, move detection, and multiple comparison modes for developers
Compare at line, word, or character level with intelligent highlighting for precise difference detection and analysis.
Auto-detect programming languages and apply syntax highlighting for JavaScript, Python, HTML, CSS, JSON, and more.
Intelligent algorithm to detect when code blocks or functions have been moved rather than deleted and re-added.
Choose between side-by-side split view for detailed comparison or unified view for traditional diff output.
Filter out whitespace changes, case differences, or empty lines to focus on meaningful code changes.
All comparisons happen locally in your browser. Your code never leaves your device, ensuring complete privacy.
From code reviews to merge conflicts, our diff tool adapts to your needs
Review pull requests and code changes with advanced diff visualization that highlights moved functions and renamed variables.
Resolve Git merge conflicts by comparing branches side-by-side with clear visualization of conflicting changes.
Track changes in configuration files, documentation, or any text-based content with precise difference detection.
Compare before and after versions of optimized code to understand the impact of performance improvements.
Everything you need to know about comparing code and text files
Our tool supports syntax highlighting for JavaScript, TypeScript, Python, Java, C++, HTML, CSS, JSON, XML, and plain text, with automatic language detection.
Our algorithm analyzes code blocks and functions to detect when they've been moved to different locations rather than deleted and re-added, showing clear move indicators.
Yes! You can upload text files, code files, or any text-based document for comparison. All processing happens locally for complete privacy.
Line comparison shows differences between entire lines, word comparison highlights changed words within lines, and character comparison shows precise character-level changes.
Absolutely! All comparisons happen entirely in your browser. Your code is never uploaded to our servers or shared with anyone.
Yes, you can filter out whitespace changes, case differences, and empty lines to focus only on meaningful content changes.
