Install Netcode for GameObjects

Multiple methods are available to install the Netcode for GameObjects (Netcode) package. This guide details how to install the develop branch of Netcode.

In-Progress Development

All features and code available in the develop branch is in-progress and not final. All cloned code may change daily or weekly, depending on submitted pull requests. All documentation and release notes for the develop version are not final.

Clone the repo#

You need to clone the code repo locally to work with in-development code.

First, install Git if you do not have it installed on your PC. After installing Git, restart your system. A full restart is required to update for Git or you may receive an error adding packages.

Next, decide on how you want to clone: command line or application.

Git Commands#

To clone with Git commands:

  1. Open a command line terminal.

  2. Change directory to a location on your local.

  3. Enter a command to clone. Example commands:

    • Git CLI: git clone
    • GitHub CLI: gh repo clone Unity-Technologies/com.unity.netcode.gameobjects
  4. All files clone locally.

GitHub Desktop#

To clone with GitHub Desktop:

  1. Install GitHub Desktop.
  2. Through the GitHub repository, select Code > Open with GitHub Desktop option.
  3. Select a location to clone to and complete cloning.

To clone directory through GitHub Desktop:

  1. Open the application.

  2. Click File > Clone Repository.

  3. Select the URL tab, copy and paste the repository URL:
  4. Click Clone.

Open the develop branch#

To run the develop branch of Netcode:

  1. Checkout the develop branch of Netcode using Git commands or application like GitHub Desktop.

  2. Open Unity Hub and click Add.

  3. Navigate to the cloned GitHub repository and select the testproject folder.

    You should see Custom installed packages available in develop, such as Netcode Networking Library and Unity Transport for Netcode.


Updated Local Code

We recommend updating your local clone often from the Netcode repository. This branch is constantly updated with new and updated features, fixed issues, and more.


If you want to make changes to develop code and content, you may want to create a local branch off of develop. Keep your branch updated from the remote develop branch to access fixes and updated features. Do not attempt to merge commits to the develop branch back into the respository. If you want to contribute, see Netcode Contributing guidelines.

Next Steps#

See the following content to continue your journey using Netcode:


Errors with incorrect package loading

If you receive a different package than Netcode when adding the URL to Unity Hub, you may have not correctly copied the GitHub URL.

Hover over the URL to copy, click the Copy function in the code block, and use this when adding the package from a Git URL in Unity Hub.

Errors adding package

MacOS users may receive the following errors:

  • Cannot perform upm operation: Unable to add package... Error when executing git command. xcrun: error: invalid active developer path
  • Error adding package...

These are common errors for MacOS users that have not installed or updated Xcode or Xcode developer tools. You may need to upgrade your Xcode installation. In a terminal, use this command: xcode-select --install.

If you newly installed or updated Git, you may also need to restart your system. Restarting Unity may not be enough if you added Git and could receive a package loading error.

Errors finding Git installation

If you receive an OS or Unity error trying to locate Git after updating or installing Git, you need to fully restart your computer. Restarting only Unity may not fully update system information to correctly locate the install.

VPN or Proxy Errors

If you use VPN or proxy software from international locations, you may encounter access issues. Consider turning off your VPN service or selecting a different location.
