Manage multiple related repositories as a single workspace with synchronized branches, linked pull requests, and atomic merges.

Inspired by Android's repo tool, gitgrip brings manifest-based multi-repo management to any project.

Features

• Manifest-based configuration - Define all your repos in a single YAML file
• Multi-platform support - Works with GitHub, GitLab, and Azure DevOps (even mixed in one workspace)
• Synchronized branches - Create and checkout branches across all repos at once
• Linked PRs - Create pull requests that reference each other across repos
• Atomic merges - All-or-nothing merge strategy ensures repos stay in sync
• Status dashboard - See the state of all repos at a glance

Installation

Homebrew (macOS/Linux)

brew tap laynepenney/tap
brew install gitgrip

From crates.io

cargo install gitgrip

From GitHub Releases

Pre-built binaries for Linux, macOS (Intel & Apple Silicon), and Windows are available on the releases page.

From Source

git clone https://github.com/laynepenney/gitgrip.git
cd gitgrip
cargo build --release

# Binary is at target/release/gr (or gr.exe on Windows)
# Install to ~/.cargo/bin:
cargo install --path .

Quick Start

1. Create a manifest repository

Create a new repo to hold your workspace manifest (e.g., my-workspace), then add a manifest.yaml:

version: 1

manifest:
  url: git@github.com:your-org/my-workspace.git

repos:
  frontend:
    url: git@github.com:your-org/frontend.git
    path: ./frontend
    default_branch: main

  backend:
    url: git@github.com:your-org/backend.git
    path: ./backend
    default_branch: main

  shared:
    url: git@github.com:your-org/shared-libs.git
    path: ./shared
    default_branch: main

settings:
  pr_prefix: "[cross-repo]"
  merge_strategy: all-or-nothing

2. Initialize a workspace

From a manifest URL:

gr init git@github.com:your-org/my-workspace.git

From existing local directories:

# Auto-scan current directory for git repos
gr init --from-dirs

# Scan specific directories
gr init --from-dirs --dirs ./frontend ./backend

# Interactive mode - preview and edit manifest before saving
gr init --from-dirs --interactive

This creates .gitgrip/manifests/ with the manifest configuration.

3. Start working

# Check status of all repos
gr status

# Create a feature branch across all repos
gr branch feature/new-feature

# Make changes, commit in each repo, then create linked PRs
gr pr create --title "Add new feature"

# Sync all repos with latest from remote
gr sync

Command Details

gr init <manifest-url>

Initialize a new workspace by cloning the manifest repository and all defined repos.

gr init --from-dirs

Initialize a workspace from existing local git repositories. Discovers repos, extracts remote URLs and default branches, and generates a manifest.

Option	Description
--from-dirs	Create workspace from existing directories
--dirs <paths>	Specific directories to scan (default: all subdirs)
-i, --interactive	Preview manifest and confirm before writing

Features:

• Auto-detects remote URLs and default branches
• Handles duplicate directory names with auto-suffixing
• Initializes manifest as a git repository with initial commit
• In interactive mode, edit the generated YAML before saving

gr sync [options]

Pull latest changes from the manifest and all repositories.

Option	Description
--fetch	Fetch only, don't merge
--no-link	Skip processing copyfile/linkfile entries
--no-hooks	Skip running post-sync hooks

gr status

Show status of all repositories including branch, changes, and sync state.

gr branch [name]

Create a new branch across all repositories, or list existing branches.

Option	Description
-r, --repo <repos...>	Only operate on specific repos
--include-manifest	Include manifest repo

gr pr create

Create linked PRs across repos with changes.

Option	Description
-t, --title <title>	PR title
-b, --body <body>	PR body
-d, --draft	Create as draft
--push	Push branches first

gr pr merge

Merge all linked PRs atomically.

Option	Description
-m, --method <method>	merge, squash, or rebase
--no-delete-branch	Keep branches after merge
-f, --force	Merge even if checks pending

gr repo add <url>

Add a new repository to the workspace. Parses the URL, updates the manifest, and optionally clones the repo.

Option	Description
--path <path>	Local path (default: ./<repo-name>)
--name <name>	Name in manifest (default: from URL)
--branch <branch>	Default branch (default: main)
--no-clone	Only update manifest, skip cloning

If the workspace is on a feature branch, the new repo will be checked out to that branch automatically.

gr forall -c "<command>"

Run a command in each repository (like AOSP's repo forall).

Option	Description
-c, --command	Command to run (required)
-r, --repo <repos...>	Only run in specific repos
--include-manifest	Include manifest repo
--continue-on-error	Continue if command fails

Environment variables available in command:

• REPO_NAME - Repository name
• REPO_PATH - Absolute path to repo
• REPO_URL - Repository URL

Manifest Format

The manifest file (manifest.yaml) defines your workspace:

version: 1

manifest:
  url: git@github.com:your-org/workspace.git

repos:
  repo-name:
    url: git@github.com:your-org/repo.git
    path: ./local-path
    default_branch: main

settings:
  pr_prefix: "[cross-repo]"
  merge_strategy: all-or-nothing

Merge Strategies

• all-or-nothing - All linked PRs must be approved before any can merge
• independent - PRs can be merged independently

Multi-Platform Support

gitgrip supports multiple hosting platforms. The platform is auto-detected from the repository URL.

Supported Platforms

Platform	URL Patterns
GitHub	git@github.com:org/repo.git, https://github.com/org/repo.git
GitLab	git@gitlab.com:group/repo.git, https://gitlab.com/group/repo.git
Azure DevOps	git@ssh.dev.azure.com:v3/org/project/repo, https://dev.azure.com/org/project/_git/repo

Authentication

Each platform requires its own authentication:

GitHub:

export GITHUB_TOKEN=your-token
# or
gh auth login

GitLab:

export GITLAB_TOKEN=your-token
# or
glab auth login

Azure DevOps:

export AZURE_DEVOPS_TOKEN=your-pat
# or
az login

Mixed-Platform Workspaces

A single manifest can contain repos from different platforms:

repos:
  frontend:
    url: git@github.com:org/frontend.git
    path: ./frontend

  backend:
    url: git@gitlab.com:org/backend.git
    path: ./backend

  infra:
    url: https://dev.azure.com/org/project/_git/infra
    path: ./infra

Self-Hosted Instances

For GitHub Enterprise, GitLab self-hosted, or Azure DevOps Server, add a platform config:

repos:
  internal:
    url: git@gitlab.company.com:team/repo.git
    path: ./internal
    platform:
      type: gitlab
      baseUrl: https://gitlab.company.com

Griptrees (Multi-Branch Workspaces)

Work on multiple branches simultaneously without switching. Griptrees use git worktrees to create parallel workspace directories.

# Create a griptree for a feature branch
gr tree add feat/new-feature

# Creates a sibling directory with all repos on that branch:
# ../feat-new-feature/
#   ├── frontend/
#   ├── backend/
#   └── shared/

# Work in the griptree
cd ../feat-new-feature
gr status

# List all griptrees
gr tree list

# Lock to prevent accidental removal
gr tree lock feat/new-feature

# Remove when done (branches are preserved)
gr tree remove feat/new-feature

Benefits:

• No branch switching required
• Shared git objects (fast creation, minimal disk usage)
• Independent working directories

Shorthand

Use gr as the primary command:

gr status
gr sync
gr branch feature/foo

The long form gitgrip also works.

Shell Completions

Generate shell completions for tab completion:

# Bash
gr completions bash > ~/.local/share/bash-completion/completions/gr
# Or add to ~/.bashrc:
eval "$(gr completions bash)"

# Zsh
gr completions zsh > ~/.zfunc/_gr
# Or add to ~/.zshrc:
eval "$(gr completions zsh)"

# Fish
gr completions fish > ~/.config/fish/completions/gr.fish

# PowerShell
gr completions powershell >> $PROFILE

Supported shells: bash, zsh, fish, elvish, powershell

Requirements

• Git
• Platform CLI (optional, for token auth fallback):
  • GitHub: gh CLI
  • GitLab: glab CLI
  • Azure DevOps: az CLI

Legacy TypeScript Version

The original TypeScript implementation is available in the typescript-legacy/ directory and on npm as gitgrip. The Rust version is now the primary implementation with better performance and additional features.
