Tool Open source
BlazeDiff is an open-source diff ecosystem for JavaScript applications and other runtimes. It provides pixel-perfect image comparison, Rust and SIMD-based native and WebAssembly diff engines, structured image-diff interpretation, object diffing, perceptual metrics including SSIM, MS-SSIM, Hitchhiker's SSIM, and GMSD, and a from-scratch Rust PNG codec.
The ecosystem includes JavaScript, Rust, Python, and command-line packages, along with framework-agnostic and React UI components for visualizing differences. Its agentic visual-regression tool discovers routes, captures deterministic screenshots, and sends ambiguous diffs to a coding agent for a verdict.
