The web-based editor

Use the Webベースエディタ from your repository or pull request to create and commit changes.

Note: The Webベースエディタ is currently in beta preview. You can provide feedback in our Discussions.

Webベースエディタ について

The Webベースエディタ introduces a lightweight editing experience that runs entirely in your browser. With the Webベースエディタ, 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 Webベースエディタ is available to everyone for free on

The Webベースエディタ 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 Webベースエディタ 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.

Opening the Webベースエディタ

You can open any GitHub repository in the Webベースエディタ 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, hold down the shift key and press ..

  • Change the URL from "" to "".

  • When viewing a file, use the dropdown menu next to and select Open in

Codespaces and the Webベースエディタ

Both the Webベースエディタ and GitHub Codespaces allow you to edit your code straight from your repository. However, both have slightly different benefits, depending on your use case.

料金無料.Costs for compute and storage. For information on pricing, see "Codespaces pricing."
利用の可否Available to everyone on for organizations using GitHub Team or GitHub Enterprise Cloud.
Start upThe Webベースエディタ 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."
ComputeThere is no associated compute, so you won’t be able to build and run your code or use the integrated terminal.With Codespaces, you get the power of dedicated VM on which you can run and debug your application.
Terminal accessなし.Codespaces provides a common set of tools by default, meaning that you can use the Terminal exactly as you would in your local environment.
ExtensionsOnly 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 Codespaces, you can use most extensions from the Visual Studio Code Marketplace.

Continue working on Codespaces

You can start your workflow in the Webベースエディタ and continue working on a codespace, provided you have access to Codespaces. If you try to access the Run and Debug View or the Terminal, you'll be notified that they are not available in the Webベースエディタ.

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 the Webベースエディタ, 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 the web-based editor 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.

Working with an existing pull request

You can use the Webベースエディタ to work with an existing pull request.

  1. Browse to the pull request you'd like to open in the Webベースエディタ.
  2. Press . to open the pull request in the Webベースエディタ.
  3. Once you have made any changes, commit them using the steps in Commit your changes. Your changes will be committed directly to the branch, it's not necessary to push the changes.

Using extensions

The Webベースエディタ supports VS Code extensions that have been specifically created or updated to run in the web. These extensions are known as "web extensions". To learn how you can create a web extension or update your existing extension to work for the web, see "Web extensions" in the VS Code documentation.

Extensions that can run in the Webベースエディタ will appear in the Extensions View and can be installed. If you use Settings Sync, any compatible extensions are also installed automatically. For information, see "Settings Sync" in the VS Code documentation.


If you have issues opening the Webベースエディタ, try the following:

  • Make sure you are signed in to GitHub.
  • Disable any ad blockers.
  • Use a non-incognito window in your browser to open the Webベースエディタ.

Known limitations

  • The Webベースエディタ is currently supported in Chrome (and various other Chromium-based browsers), Edge, Firefox, and Safari. We recommend that you use the latest versions of these browsers.
  • Some keybindings may not work, depending on the browser you are using. These keybinding limitations are documented in the "Known limitations and adaptations" section of the VS Code documentation.
  • . may not work to open the Webベースエディタ according to your local keyboard layout. In that case, you can open any GitHub repository in the Webベースエディタ by changing the URL from to
