Type-Safe
TypeScript support out of the box
BlazeDiff is a high-performance diff checking ecosystem. Built with cutting-edge algorithms and optimized for speed, BlazeDiff provides tools for comparing content, visualizing differences, and integrating diff functionality into your applications.
Use Cases
Detect Different Pixels
The fastest single-threaded image diff in the world. Native Rust implementation with SIMD optimization, 3-4x faster than odiff.
JavaScript implementation of the BlazeDiff image comparison library. 1.5x faster than pixelmatch while maintaining identical accuracy.
Command-line interface for the BlazeDiff image comparison library.
Compare Perceptual Quality
SSIM (Structural Similarity Index) implementations including standard SSIM, MS-SSIM, and Hitchhiker’s SSIM for perceptual image quality measurement.
GMSD (Gradient Magnitude Similarity Deviation) metric for perceptual image quality assessment.
Find Object Inequalities
Lightning-fast structural object comparison with detailed change tracking.
Integrate in Your Tests
Use BlazeDiff in your Jest tests with a minimal setup.
Visualize Differences
Build image comparison interfaces with Web or React Components.
