About the github.dev editor
The github.dev editor introduces a lightweight editing experience that runs entirely in your browser. With the github.dev editor, you can navigate files and source code repositories from GitHub, and make and commit code changes. You can open any repository, fork, or pull request in the editor.
The github.dev editor is available to everyone for free on GitHub.com.
The github.dev editor provides many of the benefits of Visual Studio Code, such as search, syntax highlighting, and a source control view. You can also use Settings Sync to share your own VS Code settings with the editor. For more information, see "Settings Sync" in the VS Code documentation.
The github.dev editor runs entirely in your browser’s sandbox. The editor doesn’t clone the repository, but instead uses the GitHub Repositories extension to carry out most of the functionality that you will use. Your work is saved in the browser’s local storage until you commit it. You should commit your changes regularly to ensure that they're always accessible.
You must be signed in to GitHub.com to use the github.dev editor.
Opening the github.dev editor
You can open any GitHub repository in github.dev in either of the following ways:
-
To open the repository in the same browser tab, press . while browsing any repository or pull request on GitHub.
To open the repository in a new browser tab, press >.
-
Change the URL from "github.com" to "github.dev".
-
When viewing a file, use the dropdown menu next to and select Open in github.dev.
Codespaces and github.dev
Both github.dev and GitHub Codespaces allow you to edit your code straight from your repository. However, both have slightly different benefits, depending on your use case.
| github.dev | GitHub Codespaces | |
|---|---|---|
| Cost | Free. | Free monthly quota of usage for personal accounts. For information on pricing, see "About billing for GitHub Codespaces." |
| Availability | Available to everyone on GitHub.com. | Available to everyone on GitHub.com. |
| Start up | github.dev opens instantly with a key-press and you can start using it right away, without having to wait for additional configuration or installation. | When you create or resume a codespace, the codespace is assigned a VM and the container is configured based on the contents of a devcontainer.json file. This set up may take a few minutes to create the environment. For more information, see "Creating a codespace for a repository." |
| Compute | There is no associated compute, so you won’t be able to build and run your code or use the integrated terminal. | With GitHub Codespaces, you get the power of a dedicated VM on which you can run and debug your application. |
| Terminal access | None. | GitHub Codespaces provides a common set of tools by default, meaning that you can use the Terminal exactly as you would in your local environment. |
| Extensions | Only a subset of extensions that can run in the web will appear in the Extensions View and can be installed. For more information, see "Using extensions." | With GitHub Codespaces, you can use most extensions from the Visual Studio Code Marketplace. |
Continue working on Codespaces
You can start your workflow in github.dev and continue working on a codespace. If you try to access the Run and Debug View or the Terminal, you'll be notified that they are not available in github.dev.
To continue your work in a codespace, click Continue Working on… and select Create New Codespace to create a codespace on your current branch. Before you choose this option, you must commit any changes.
Using source control
When you use github.dev, all actions are managed through the Source Control View, which is located in the Activity Bar on the left hand side. For more information on the Source Control View, see "Version Control" in the VS Code documentation.
Because github.dev uses the GitHub Repositories extension to power its functionality, you can switch branches without needing to stash changes. For more information, see "GitHub Repositories" in the VS Code documentation.
Create a new branch
- If the current branch is not shown in the status bar, at the bottom of your codespace, right-click the status bar and select Source control.
- Click the branch name in the status bar.
