koola/pixel-diff

Pixel-Diff is a lightweight image comparison tool designed for comparing screenshots and other images, continuing the work of BlinkDiff. It supports three types of comparisons: pixel-by-pixel, perceptual, and context-based, making it ideal for developers testing visual consistency in web applications, rendering engines, or photo manipulation tools. The tool is easy to install via npm and provides configurable thresholds and output options for detailed analysis.
