To manually download a .vsix file for a Visual Studio Code (VS Code) extension, you can use the Visual Studio Marketplace, which hosts all official extensions. The .vsix file is the packaged format for VS Code extensions, and while the Marketplace doesn’t always provide a direct download button, you can construct the download URL or use alternative methods. Here’s how to do it step-by-step:

Steps to Manually Download a .vsix File

1. Find the Extension on the Visual Studio Marketplace
   • Go to the Visual Studio Marketplace in your web browser.
   • Search for the extension you want (e.g., “Python” by Microsoft, “Prettier - Code formatter”, etc.).
   • Open the extension’s page. For example, the Python extension’s URL might look like:
     https://marketplace.visualstudio.com/items?itemName=ms-python.python.
2. Identify the Publisher and Extension Name
   • On the extension’s page, note the publisher and extension identifier. These are part of the URL or displayed on the page.
   • For example, in ms-python.python, ms-python is the publisher, and python is the extension name.
3. Construct the Download URL
   • The .vsix file can be downloaded directly using a specific URL pattern provided by the Marketplace. The general format is:

     https://<publisher>.gallery.vsassets.io/_apis/public/gallery/publisher/<publisher>/extension/<extension-name>/latest/assetbyname/Microsoft.VisualStudio.Services.VSIXPackage
     

   • Replace <publisher> with the publisher’s name and <extension-name> with the extension name.
   • For the Python extension (ms-python.python), the URL would be:

     https://ms-python.gallery.vsassets.io/_apis/public/gallery/publisher/ms-python/extension/python/latest/assetbyname/Microsoft.VisualStudio.Services.VSIXPackage
     

   • Paste this URL into your browser, and it will trigger the download of the .vsix file.
4. Alternative: Use the Marketplace Page “Download Extension” Link (if available)
   • Some extension pages include a “Download Extension” link under the Resources section or elsewhere. If present, click it to download the .vsix file directly. However, this is less common, so the URL method is more reliable.
5. Verify the Download
   • The downloaded file will have a .vsix extension (e.g., ms-python.python-<version>.vsix).
   • Check the file size and name to ensure it matches the extension and version you expect.
6. Install the .vsix File in VS Code (Optional)
   • Open VS Code.
   • Go to the Extensions view (Ctrl+Shift+X or Cmd+Shift+X on macOS).
   • Click the three-dot menu (...) at the top-right of the Extensions pane.
   • Select Install from VSIX, then browse to and select the downloaded .vsix file.

Example Walkthrough

Let’s say you want the ESLint extension by Dirk Baeumer:

• Marketplace URL: https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint
• Publisher: dbaeumer
• Extension name: vscode-eslint
• Download URL:

  https://dbaeumer.gallery.vsassets.io/_apis/public/gallery/publisher/dbaeumer/extension/vscode-eslint/latest/assetbyname/Microsoft.VisualStudio.Services.VSIXPackage
  

• Open this URL in your browser, and the .vsix file (e.g., dbaeumer.vscode-eslint-<version>.vsix) will download.

Notes

• Version: The /latest/ part of the URL ensures you get the most recent version. If you need a specific version, you’d typically need access to the version number (visible on the Marketplace’s “Version History” tab) and might need to adjust the URL or use a tool like ovsx (see below), though the Marketplace API doesn’t always expose older versions easily via direct URL.
• Blocked Downloads: If the URL doesn’t work, the publisher might restrict direct access, or your browser/network might block it. In such cases, try a different browser or a download manager.
• Alternative Tools: You can use a command-line tool like ovsx (from the Open VSX Registry) to download extensions. Install it via npm (npm install -g ovsx), then run:

  ovsx download ms-python.python
  

  This downloads the .vsix file programmatically.

Final Answer

To manually download a .vsix file for a VS Code extension:

1. Go to the extension’s page on the Visual Studio Marketplace.
2. Identify the publisher and extension name (e.g., ms-python.python).
3. Use this URL format in your browser:

   https://<publisher>.gallery.vsassets.io/_apis/public/gallery/publisher/<publisher>/extension/<extension-name>/latest/assetbyname/Microsoft.VisualStudio.Services.VSIXPackage
   

4. Download the .vsix file and optionally install it in VS Code.
