You can create a codespace on GitHub.com, in Visual Studio Code, or by using GitHub CLI. Use the tabs in this article to display instructions for each of these ways of creating a codespace.
If you're starting a new project, you might want to create a codespace from a template and publish to a repository on GitHub Enterprise Cloud later. For more information, see "Creating a codespace from a template."
Note: If you use a JetBrains IDE, you can use GitHub CLI to create a codespace. You can then use the JetBrains Gateway application to open the codespace in a JetBrains IDE. For more information, see "Using Codespaces in your JetBrains IDE."
You can use GitHub Codespaces on your personal GitHub.com account, with the quota of free use included each month for accounts on the Free and Pro plans. You can continue using GitHub Codespaces beyond your monthly included storage and compute usage by providing payment details and setting a spending limit. For more information, see "About billing for GitHub Codespaces."
Organizations can enable members and outside collaborators to create and use codespaces at the organization's expense. For more information, see "Enabling GitHub Codespaces for your organization."
Each codespace you create is only available to you. No one else can work in your codespace.
If you create a codespace from a repository, the codespace will be associated with a specific branch, which cannot be empty. You can create more than one codespace per repository or even per branch.
You can see every available codespace that you have created at github.com/codespaces.
When you create a codespace, a number of steps happen to create and connect you to your development environment:
- Step 1: VM and storage are assigned to your codespace.
- Step 2: Container is created and your repository is cloned.
- Step 3: You can connect to the codespace.
- Step 4: Codespace continues with post-creation setup.
For more information on what happens when you create a codespace, see "Deep Dive."
For more information on the lifecycle of a codespace, see "The codespace lifecycle."
If you want to use Git hooks for your codespace, then you should set up hooks using the
devcontainer.json lifecycle scripts, such as
postCreateCommand, during step 4. Since your codespace container is created after the repository is cloned, any git template directory configured in the container image will not apply to your codespace. Hooks must instead be installed after the codespace is created. For more information on using
postCreateCommand, see the
devcontainer.json reference in the VS Code documentation.
You can edit code, debug, and use Git commands while developing in a codespace with VS Code. For more information, see the VS Code documentation.
To speed up codespace creation, repository administrators can enable GitHub Codespaces prebuilds for a repository. For more information, see "About GitHub Codespaces prebuilds."
On GitHub.com, navigate to the main page of the repository.
Under the repository name, use the "Branch" dropdown menu, and select the branch you want to create a codespace for.
Click the Code button, then click the Codespaces tab.
If codespaces for this repository are billable to an organization, or its parent enterprise, a message is displayed below the Create codespace on BRANCH button telling you who will pay for the codespace.
Create your codespace, either using the default options, or after configuring advanced options:
Use the default options
To create a codespace using the default options, click the plus sign (). Alternatively, if you don't currently have any codespaces for this repository, you can click Create codespace on BRANCH.
To configure advanced options for your codespace, such as a different machine type or a particular
Click the ellipsis (...) at the top right of the Codespaces tab and select New with options.
On the options page for your codespace, choose your preferred options from the dropdown menus.
- You can bookmark the options page to give you a quick way to create a codespace for this repository and branch.
- The https://github.com/codespaces/new page provides a quick way to create a codespace for any repository and branch. You can get to this page quickly by typing
codespace.newinto your browser's address bar.
- For more information about the
devcontainer.jsonfile, see "Introduction to dev containers."
- For more information about machine types, see "Changing the machine type for your codespace."
- Your choice of available machine types may be limited by a number of factors. These can include a policy configured for your organization, or a minimum machine type specification for your repository. For more information, see "Restricting access to machine types" and "Setting a minimum specification for codespace machines."
Click Create codespace.
After you connect your account on GitHub.com to the GitHub Codespaces extension, you can create a new codespace. For more information about the GitHub Codespaces extension, see the VS Code Marketplace.
In VS Code, in the left sidebar, click the Remote Explorer icon.
Note: If the Remote Explorer is not displayed in the Activity Bar:
- Access the Command Palette. For example, by pressing Shift+Command+P (Mac) / Ctrl+Shift+P (Windows/Linux).
- Click Codespaces: Details.
Click the Add icon: .
Type the name of the repository you want to develop in, then select it.
If the repository you choose is owned by an organization, and the organization has configured codespaces for this repository to be billable to the organization, or its parent enterprise, a message will be displayed in subsequent prompts telling you who will pay for the codespace.
Click the branch you want to develop on.
If prompted to choose a dev container configuration file, choose a file from the list.
Click the machine type you want to use.
Note: Your choice of available machine types may be limited by a number of factors. These can include a policy configured for your organization, or a minimum machine type specification for your repository. For more information, see "Restricting access to machine types" and "Setting a minimum specification for codespace machines."
To learn more about GitHub CLI, see "About GitHub CLI."
To create a new codespace, use the
gh codespace create subcommand.
gh codespace create
You are prompted to choose a repository. If codespaces for this repository are billable to an organization, or its parent enterprise, a message is displayed telling you who will pay for the codespace. You are then prompted to choose a branch, a dev container configuration file (if more than one is available), and a machine type (if more than one is available).
Alternatively, you can use flags to specify some or all of the options:
gh codespace create -r OWNER/REPO -b BRANCH --devcontainer-path PATH -m MACHINE-TYPE
In this example, replace
owner/repo with the repository identifier. Replace
branch with the name of the branch, or the full SHA hash of the commit, that you want to be initially checked out in the codespace. If you use the
-r flag without the
b flag, the codespace is created from the default branch.
path with the path to the dev container configuration file you want to use for the new codespace. If you omit this flag and more than one dev container file is available you will be prompted to choose one from a list. For more information about the dev container configuration file, see "Introduction to dev containers."
machine-type with a valid identifier for an available machine type. Identifiers are strings such as:
standardLinux32gb. The type of machines that are available depends on the repository, your personal account, and your location. If you enter an invalid or unavailable machine type, the available types are shown in the error message. If you omit this flag and more than one machine type is available you will be prompted to choose one from a list.
For full details of the options for this command, see the GitHub CLI manual.
