imgdiff is a fast command-line tool written in Go that compares two images pixel-by-pixel and optionally renders a visual diff output image. It is a performance-focused alternative to odiff, claiming roughly 3x faster comparisons on large images.
Use cases
- compare two png images pixel by pixel
- generate a visual diff image of two screenshots
- visual regression testing for web ui screenshots
- detect layout changes between two images
- fast image diffing in ci pipelines
When to choose
- you need the fastest available pixel-by-pixel image comparison from the command line
- you want a simple single-binary tool with no runtime dependencies
- you need visual diff output for screenshot testing workflows
When to avoid
- you need a library API to embed in your own application rather than a CLI
- you need active development or recent bug fixes since the last release was in 2021
- you need to compare image formats beyond what the tool supports
