日本語版はこちら

keifu (系譜, /keːɸɯ/) is a terminal UI tool that visualizes Git commit graphs. It shows a colored commit graph, commit details, and a summary of changed files, and lets you perform everyday Git operations: branch switching, staging, committing, and pushing — with full mouse support.

Motivation

• Readable commit graph — git log --graph is hard to read; keifu renders a cleaner, color-coded graph
• Fast branch switching — With the rise of vibe coding, working on multiple branches in parallel has become common. keifu makes branch switching quick and visual
• Keep it simple — Only basic Git operations are supported; this is not a full-featured Git client
• Narrow terminal friendly — Works well in split panes and small windows
• No image protocol required — Works on any terminal with Unicode support

Features

• Unicode commit graph with per-branch colors
• Commit list with branch labels, date, author, short hash, and message (some fields may be hidden on narrow terminals)
• Commit detail panel with full message and changed file stats (+/-)
• File diff view with syntax highlighting and word-level change emphasis
• Git operations: checkout, create/delete branch, fetch, stage/unstage, commit, push
• Mouse support: click to select commits/files/panes, clickable status bar hints, per-pane wheel scrolling
• Branch search with dropdown UI
• Remote-control debug server and file logging for agent-driven debugging (see docs/debugging.md)

Requirements

• Run inside a Git repository (auto-discovery from current directory)
• A terminal with Unicode line drawing support and color
• git command in PATH (required for fetch/push)
• Rust toolchain (for building from source)

Configuration

See docs/configuration.md for configuration options.

Keybindings

Navigation

Key	Action
j / ↓	Move down (scrolls the detail pane when focused)
k / ↑	Move up (scrolls the detail pane when focused)
Tab	Switch pane focus (graph / commit detail)
]	Jump to next commit that has branch labels
[	Jump to previous commit that has branch labels
h / ←	Select left branch (same commit)
l / →	Select right branch (same commit)
Ctrl+d	Page down
Ctrl+u	Page up
g / Home	Go to top
G / End	Go to bottom
@	Jump to HEAD (current branch)
Space	Open file diff view

Git operations

Key	Action
Enter	Checkout selected branch/commit
b	Create branch at selected commit
d	Delete branch (local, non-HEAD)
f	Fetch from origin
c	Commit staged changes (opens message dialog)
p	Push current branch to origin

File list (Space) / staging

Staging keys work when the "uncommitted changes" row is selected.

Key	Action
j / k	Select file
Enter	Open file diff
s	Stage / unstage selected file
a	Stage all changes
u	Unstage all changes
c	Commit staged changes
Esc / q	Back

Mouse

Input	Action
Click on a commit row	Select commit (double-click opens the file list)
Click on a file row	Select file (double-click opens the diff)
Click on a pane	Focus the pane
Click on a status bar hint	Run that action
Wheel scroll	Scrolls the pane under the cursor

Since keifu captures mouse input, use your terminal's modifier for native text selection (usually Shift + drag; Fn + drag on iTerm2).

Note: Ghostty currently fans one wheel notch out into multiple scroll events for mouse-mode apps (ghostty#3955), which can scroll a few extra lines per notch. Lowering mouse-scroll-multiplier in the Ghostty config works around it.

Search

Key	Action
/	Search branches (incremental fuzzy search)
↑ / Ctrl+k	Select previous result
↓ / Ctrl+j	Select next result
Enter	Jump to selected branch
Esc / Backspace on empty	Cancel search

File diff view

Key	Action
j / k / ↑ / ↓	Scroll up/down
h / l / ← / →	Scroll left/right
Ctrl+d / Ctrl+u	Half-page down/up
Ctrl+f / Ctrl+b	Full page down/up
g / G	Go to top/bottom
0	Scroll to line start
] / [	Jump to next/previous hunk
n / N	Jump to next/previous file
Esc / q	Back to file select / close

Other

Key	Action
y	Copy commit hash to clipboard (OSC 52)
Y	Copy branch name to clipboard (OSC 52)
R	Refresh repository data
o	Toggle remote branches
t	Toggle tags
?	Toggle help
q / Esc	Quit (returns focus to the graph first when the detail pane is focused)

Notes and limitations

• The TUI loads up to 500 commits across the visible branches.
• Merge commits are diffed against the first parent; the initial commit is diffed against an empty tree.
• Changed files are capped at 50. Binary files are shown without line stats.
• If there are staged, unstaged, or untracked changes, an "uncommitted changes" row appears at the top.
• When multiple branches point to the same commit, the label is collapsed to a single name with a +N suffix (e.g., main +2). Use h/l or ←/→ to switch between them.
• Checking out origin/xxx creates or updates a local branch. Upstream is set only when creating a new branch. If the local branch exists but points to a different commit, it is force-updated to match the remote.
• Remote branches are displayed by default. Press o to hide them; when hidden, commits reachable only from remote branches are excluded from the graph.
• Tags are displayed by default. Press t to hide them.
• Delete operations only work with local branches.
• Fetch and push require the origin remote to be configured. Staging works per file (no hunk-level staging); commits include only staged changes, like plain git commit.
