Deff – Side-by-side Git diff review in your terminal
deff is an interactive Rust TUI for reviewing git diffs side-by-side with syntax highlighting and added/deleted line tinting. It supports keyboard/mouse navigation, vim-style motions, in-diff search (/, n, N), per-file reviewed toggles, and both upstream-based and explicit --base/--head comparisons. It can also include uncommitted + untracked files (--include-uncommitted) so you can review your working tree before committing. Would love to get some feedback
In plain words
Deff is a terminal-based tool for reviewing git diffs side-by-side with syntax highlighting and color-coded additions and deletions. Built in Rust, it offers keyboard and mouse navigation, vim-style motions, search functionality, and the ability to mark files as reviewed. Developers can compare against upstream branches or specify custom base and head versions, and optionally include uncommitted and untracked files in their review.
