Innovating with GitHub Codespaces

Discover how GitHub Codespaces provides a cloud-based, flexible, and secure IDE that adapts to any workflow. Whether you’re collaborating on open source or scaling enterprise projects, Codespaces streamlines setup and accelerates development.

What Is GitHub Codespaces?

GitHub Codespaces is a fully managed, cloud-hosted development environment that brings Visual Studio Code to your browser or local VS Code client. It eliminates local machine setup and offers:

Preconfigured containers defined by a devcontainer.json
Instant, on-demand workspaces that spin up in seconds
Native GitHub integration for branch management, pull requests, and issue tracking

Getting Started with Codespaces

Install the GitHub CLI:

brew install gh       # macOS
sudo apt install gh   # Debian/Ubuntu

Authenticate:
```
gh auth login
```

Create a new Codespace:

gh codespace create --repo your-org/your-repo --branch main

Open in VS Code (locally or browser):
```
gh codespace code
```

Note

You can customize your environment by adding a .devcontainer/devcontainer.json file in your repo. See Developing inside a Container for examples.

Key Advantages of Using Codespaces

Feature	Benefit	Example CLI Command
Eliminate Legacy Limitations	Bypass outdated hardware or OS constraints	`gh codespace list`
Enhanced Flexibility	Code from any device with a browser-based editor	Access via `https://github.com/codespaces`
Robust Security Controls	Secure workspaces with built-in GitHub authentication	Integrated secrets and permission scopes
Familiar IDE Experience	Same look-and-feel as VS Code	Use extensions and settings sync
Device-Agnostic Access	No local setup; works on Windows, macOS, Linux, iPad	Supports SSH and VS Code Remote
Local VS Code Integration	Seamlessly connect local VS Code to remote Codespace	`Remote-SSH: Connect to Host…` in Command Palette (Ctrl+Shift+P)

Warning

Running Codespaces incurs cloud compute costs. Be sure to review your billing settings and stop idle codespaces to avoid unexpected charges.

How It Works

Container Configuration
Codespaces uses Docker containers defined by a devcontainer.json. This specification ensures consistent tooling and dependencies across your team.
Instant Provisioning
When you open a codespace, GitHub automatically builds your container image, checks out your code, and applies pre-defined tasks.
Integrated Tooling
Enjoy built-in support for terminals, debugging, extensions, and Git operations—just like in your local VS Code.
