delta

Delta transforms your terminal git diffs from unreadable monochrome walls into syntax-highlighted, word-level diffing with proper formatting. Set it as your git pager once and every `git diff`, `git log`, and `git blame` becomes dramatically more readable. It's the kind of small tool that makes you wonder how you lived without it.

Install it now. Seriously. It takes 30 seconds to configure and improves every git interaction. diff-so-fancy is the lighter alternative with less features. bat (by the same community) handles syntax highlighting for file viewing. The built-in git diff is the baseline nobody should accept.

The catch: It's a terminal pager, not a GUI diff tool. If you want side-by-side visual diffs with merge conflict resolution, you still need VS Code or a dedicated diff tool. Delta adds slight overhead to large diffs. And customizing themes requires editing gitconfig, which is fiddly but worth it. Literally no reason not to install this.
