A lightweight command-line tool that spins up a local web server to display Git commit diffs in a GitHub-like Files changed view - yoshiko-pg/difit

Difftastic is an experimental diff tool that compares files based on their syntax.

Code evolves, and we all spend time studying diffs. Delta aims to make this both efficient and enjoyable: it allows you to make extensive changes to the layout and styling of diffs, as well as allowing you to stay arbitrarily close to the default git/diff output.
