Monorepo vs multi-repo decision in Git - CLI Comparison

Introduction

When managing code for multiple projects, you can keep all code in one big repository or split it into many smaller ones. Choosing the right way helps teams work smoothly and avoid confusion.

When you want all your projects to share the same version history and dependencies easily.

When different teams work independently on separate projects and need clear boundaries.

When you want to simplify code sharing and refactoring across projects.

When you want to reduce complexity by isolating projects to avoid accidental changes.

When you want to control access so only certain teams can see or change specific projects.

Commands

Clone the monorepo to your local machine to work on all projects together.

Terminal

git clone https://github.com/example-org/monorepo.git

Expected Output

Cloning into 'monorepo'...

remote: Enumerating objects: 100, done.

remote: Counting objects: 100% (100/100), done.

remote: Compressing objects: 100% (80/80), done.

Receiving objects: 100% (100/100), 1.2 MiB | 2.0 MiB/s, done.

Clone a single project repository when using multi-repo to work only on that project.

Terminal

git clone https://github.com/example-org/project-a.git

Expected Output

Cloning into 'project-a'...

remote: Enumerating objects: 50, done.

remote: Counting objects: 100% (50/50), done.

remote: Compressing objects: 100% (40/40), done.

Receiving objects: 100% (50/50), 600 KiB | 1.5 MiB/s, done.

Check the current state of your working directory and staging area to see changes before committing.

Terminal

git status

Expected Output

On branch main

Your branch is up to date with 'origin/main'.



nothing to commit, working tree clean

Save your changes with a message describing what you fixed or added.

Terminal

git commit -m "Fix bug in project A module"

Expected Output

[main abc1234] Fix bug in project A module

Key Concept

If you remember nothing else, remember: monorepos keep all code in one place for easy sharing, while multi-repos separate projects for clearer boundaries and simpler access control.

Common Mistakes

Trying to manage many unrelated projects in one monorepo without clear structure

This causes confusion, harder merges, and slower operations as the repo grows.

Use folders and clear naming in monorepos or switch to multi-repos if projects are very different.

Cloning the entire monorepo when only one project is needed

This wastes time and disk space, slowing down your work.

Use sparse checkout or switch to multi-repo to clone only needed projects.

Mixing changes from different projects in one commit

This makes it hard to track what changed and why, confusing reviewers.

Commit changes per project or feature separately with clear messages.

Summary

Monorepos store all projects in one repository for easy sharing and unified history.

Multi-repos keep projects in separate repositories for clear boundaries and simpler access control.

Use git clone and git commit commands to work with either approach, adjusting your workflow accordingly.
