About Difftastic

Difftastic is a structural diff tool that compares files based on syntax rather than line-by-line text. It highlights the meaningful changes even when formatting or line wrapping changes, which makes reviews easier to read. The tool supports dozens of programming languages and is designed to integrate with Git and other VCS workflows. It is open source and maintained on GitHub, and there is also a dedicated documentation site and Rust crate metadata that track releases. If you are frustrated by noisy diffs after refactors or reformatting, Difftastic is a practical upgrade to your standard diff flow.
