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

  1. Install the GitHub CLI:
  2. Authenticate:
  3. Create a new Codespace:
  4. Open in VS Code (locally or browser):
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

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

How It Works

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