What is OmniDiff?
OmniDiff is a command-line utility designed for fast, robust, and accurate content-aware diffing. It processes both text-based source code and various binary formats, including images, fonts, PDFs, archives, and message catalogs.
The tool applies specialized algorithms tailored to specific file types rather than relying on generic line-by-line comparison. This approach delivers near-perfect accuracy across most categories while keeping processing times under one hundred milliseconds. It reliably handles approximately ninety-nine point nine five percent of code changes.
Written in Rust, OmniDiff is distributed under an open source license with a separate commercial license option. Prebuilt binaries are provided for Linux, macOS, and Windows. Users can install the software via Cargo, Homebrew, APT, Nix, or distribution-specific packaging recipes.
