What is deff?

deff is a Rust TUI for interactive side-by-side git diff reviews, turning raw change output into a navigable viewer with per-file hopping, independent vertical/horizontal scrolling, syntax highlighting, and add/delete line tinting. Run it in any repo with `deff` for local branch vs upstream diffs, or `deff --strategy range --base origin/main --include-uncommitted` to check working tree changes before committing. It solves terminal diff fatigue—no more paging through `git diff` or firing up a browser for local previews.

Why is it gaining traction?

It beats static tools like delta or diff-so-fancy with vim-style keys (hjkl, Ctrl-u/d), mouse wheel (shift for horizontal), in-diff search (/ then n/N), and hunk jumping ({/}). Reviewed file marks persist in .git, perfect for multi-session PR self-reviews without rechecking everything. Developers hook on the editor-like feel in a lightweight binary, no extensions needed.

Who should use this?

Terminal-first devs reviewing feature branches against upstream, like backend engineers validating Rust/Go/Python changes pre-push. Solo contributors auditing uncommitted work, or CLI workflow fans ditching VS Code git views for speed. Avoid if you rely on graphical diff tools or non-TTY setups.

Verdict

Grab it via the one-liner installer if you're in git daily—features deliver immediate value. With 294 stars and 1.0% credibility, it's immature but functional; strong README and tests, though scale to huge diffs unproven.
