codey

A review-first Git TUI for agentic coding workflows. Two-section staged/unstaged diff viewer with transient line comments, real git staging, and a commit log sidebar with per-commit file trees, pull/push, and commit creation. Built on OpenTUI and hunk-diff.

codey sits beside your agent while it writes code. Review the diff it just produced, comment on lines, stage the parts you want, and hand the notes back. It runs standalone in any terminal and as a herdr plugin pane.

codey ships 57+ bundled themes. See Themes for the full list.

Installation

Install globally from npm. A prebuilt binary for your platform is fetched automatically, so no bun and no Node dependencies are required at runtime.

npm install -g @rodey-io/codey

# or with bun's faster installer
bun add -g @rodey-io/codey

codey

The npm package ships a small JS shim plus prebuilt binaries for macOS (arm64, x64) and Linux (x64, arm64, glibc and musl), published as @rodey-io/codey-<os>-<arch>[-musl] platform packages. On Alpine Linux (musl) the binary needs a couple of system libraries:

apk add libstdc++ libgcc

You can also install manually from the GitHub Releases page. Download the codey-<version>-<os>-<arch>[-musl].tar.gz asset for your platform, extract it, and put the codey binary on your PATH.

As a herdr plugin (recommended for agentic workflows)

# Install from GitHub (downloads the matching release binary)
herdr plugin install rodeyseijkens/codey

# Open the pane
herdr plugin action invoke open --plugin codey

herdr clones the repo and runs herdr/build.sh, which installs the standalone GitHub Release binary for this platform into the plugin directory. If no prebuilt exists, it installs deps and compiles a standalone binary from source (requires bun, and pnpm for OpenTUI native packages).

Getting started

Run codey in a repository. The default view splits your staged and unstaged changes into two sections. Press ? for the full key list.

A first pass through the app:

1. Move through the sidebar rows with j/k and open a file's diff in the diff pane.
2. Stage changes with a (current file) or A (all of them). Unstage with u/U.
3. Comment on a line or range: v to start a selection, c to add a comment, s to send.
4. Commit: focus the commit log with 2, press c, type the message, then Enter.
5. Pull and push from the commit pane with p and P.

Esc cancels overlays; q quits.

Keybindings (defaults)

Keys are grouped by the pane they act on, matching the help overlay.

Changes Pane

Key	Action
j / k	Move selection down / up
f / F	Next / previous file
Space	Collapse/expand row (section, folder, commit)
b	Toggle sidebar
t	Toggle tree / list view for the focused pane
< / >	Shrink / grow sidebar (also shift+←/→ or shift+h/l)
a / A	Stage file / Stage all files
E	Open the selected file in $EDITOR (same terminal)
u / U	Unstage staged file / discard-all is cursor-aware: U unstages all when the cursor is in the staged section, otherwise discards all working-tree changes
r	Refresh (reload from git)
m	Cycle layout (split / stack / auto)
w	Toggle line wrapping

Diff Pane

Key	Action
[ / ]	Previous / next hunk
Ctrl+f / Ctrl+b	Page down / up
Ctrl+d / Ctrl+u	Half-page down / up
v	Start line/range selection for comments
c	Add transient comment; in the commit log, open a commit input
d / e	Delete / edit comment on current line
E	Open the shown file in $EDITOR (same terminal)
n / N	Next / previous comment
s	Send comments (standalone: copy to clipboard)
y	Copy selection to clipboard

Commits Pane

Key	Action
j / k	Move selection down / up
f / F	Next / previous file
Space	Expand/collapse commit or folder
t	Toggle tree / list view for the commit file list
shift+↑/↓	Make the commit pane taller / shorter (also shift+k / shift+j)
c	Open commit input
p / P	Pull / push to the remote
g	Edit selected commit (squash/fixup/drop/amend/reword/reset)
E	Open the file row under the cursor in $EDITOR
Alt+j / Alt+k	Reorder commit up / down in history (interactive rebase)

Global

Key	Action
Tab / Shift+Tab	Cycle focus: changes ↔ diff ↔ commit log
0 / 1 / 2	Focus diff / changes / commit log directly
?	Show help overlay
q	Quit
Esc	Cancel overlay

All keybindings are customizable in ~/.config/codey/config.toml under [keybindings]. Press ? inside the app for the full live list.

Configuration

Layouts (split / stack / auto), themes, line numbers, tab width, the changes pane view (changesFileView, default tree) and the commit file list view (commitFilesView, default list), ignored files, the file editor, and custom keybindings live in ~/.config/codey/config.toml.

Set theme to any bundled theme id, or leave it at auto for the default theme. See Themes for the list.

# ~/.config/codey/config.toml
theme = "tokyo-night"

E opens the focused file in the same terminal. Set editor to pick the program; otherwise codey uses $VISUAL, then $EDITOR, then vi.

# ~/.config/codey/config.toml
editor = "nvim"

Ignoring files in the diff

Lock files and dependency checksums are not loaded into the diff view by default: package-lock.json, pnpm-lock.yaml, yarn.lock, bun.lock, bun.lockb, Cargo.lock, Gemfile.lock, poetry.lock, Pipfile.lock, go.sum, composer.lock, Package.resolved, packages.lock.json, pubspec.lock, uv.lock, mix.lock, deno.lock, flake.lock, .terraform.lock.hcl, and gradle.lockfile. They still appear in the file list: selecting one shows a placeholder instead of its diff.

Set ignoreFiles to replace the default list with your own glob patterns. Patterns match the repo-relative path; * matches within a path segment, ** crosses directories, and ? matches a single character. A pattern without / matches that name at any depth. An empty list disables the filter.

# ~/.config/codey/config.toml
ignoreFiles = ["**/package-lock.json", "**/pnpm-lock.yaml", "**/*.snap"]
