If you are looking for a scripted solution:

Get binary download URL: you can use an API, but be warned that there is no documentation for it. This API can return an URL to download .vsix files (see example below)
Download the binary
Carefully unzip the binary into ~/.vscode/extensions/: you need to modify unzipped directory name, remove one file and move/rename another one.

For API start by looking at following example, and for hints how to modify request head to https://github.com/Microsoft/vscode/blob/master/src/vs/platform/extensionManagement/common/extensionGalleryService.ts.

POST https://marketplace.visualstudio.com/_apis/public/gallery/extensionquery?api-version=5.1-preview HTTP/1.1
content-type: application/json

{
    "filters": [
        {
        "criteria": [
            {
                "filterType": 8,
                "value": "Microsoft.VisualStudio.Code",
            },
            {
                "filterType": 7,
                "value": "ms-python.python",
            }
        ],
        "pageNumber": 1,
        "pageSize": 10,
        "sortBy": 0,
        "sortOrder": 0,
        }
    ],
    "assetTypes": ["Microsoft.VisualStudio.Services.VSIXPackage"],
    "flags": 514,
}

Explanations to the above example:

"filterType": 8 - FilterType.Target more FilterTypes
"filterType": 7 - FilterType.ExtensionName more FilterTypes
"flags": 514 - 0x2 | 0x200 - Flags.IncludeFiles | Flags.IncludeLatestVersionOnly - more Flags
- to get flag decimal value you can run python -c "print(0x2|0x200)"
"assetTypes": ["Microsoft.VisualStudio.Services.VSIXPackage"] - to get only link to .vsix file more AssetTypes

UPDATE 2017-12-13  You can now download the extension directly from the marketplace     As of Visual Studio Code 1 7 1 dragging or opening the extension does not work any more  In order to install it manually you need to    open the extensions sidebar click on the ellipsis in the right upper corner choose Install from VSIX       Old Method  According to the documentation it is possible to download an extension directly      An extension s direct download URL is in the form   https     publisher  gallery vsassets io  apis public gallery publisher   publisher  extension   extension name    version  assetbyname Microsoft VisualStudio Services VSIXPackage    This means that in order to download the extension you need to know   the publisher name the version the extension name   You can find all this information in the URL   Example  Here s an example for downloading an installing the C  v1 3 0 extension   Publisher  Extension and Version  You can find the publisher and the extension names on the extension s homepage inside its URL      https   marketplace visualstudio com items itemName ms-vscode csharp   Here the publisher is ms-vscode and the extension name is csharp   The version can be found on the right side in the More Info area   To download it you need to create a link from the template above      https   ms-vscode gallery vsassets io  apis public gallery publisher ms-vscode extension csharp 1 3 0 assetbyname Microsoft VisualStudio Services VSIXPackage   All packages will have the same name Microsoft VisualStudio Services VSIXPackage  so you ll need to rename it after downloading if you want to know what package it was later   Installation  In order to install the extension   Rename the file and give it the   vsix extension Open Visual Studio Code  go to menu File  rarr  Open File    or Ctrl   O and select the  vsix file If everything went fine  you should see this message at the top of the window       Extension was successfully installed  Restart to enable it

All these suggestions are great  but kind of painful to follow because executing the code to construct the URL or constructing that crazy URL by hand is kind of annoying     So  I threw together a quick web app to make things easier  Just paste the URL of the extension you want and out comes out the download of your extension already properly named  publisher-extension-version vsix   Hope someone finds it helpful  http   vscode-offline herokuapp com

If you have a specific  legacy  version of VSCode on your offline instance  pulling the latest extensions might not properly integrate   To make sure that VSCode and the extensions work together  they must all be installed together on the online machine  This resolves any dependencies  with specific versions   and ensures the exact configuration of the offline instance    Quick steps   Install the VSCode version  turn off updating  and install the extensions  Copy the extensions from the installed location and place them on the target machine    Detailed steps   Install the exact version of VSCode on online machine  Then turn off updates by going to File - gt  Preferences - gt  Settings  In the Settings window  under User Settings - gt  Application  go to Update section  and change the parameter for Channel to none  This prevents VSCode from reaching out to the internet and auto-updating your versions to the latest   Then go to the VSCode extensions section and install all of your desired extensions  Copy the installed extensions from their install location  with windows its C  Users  lt username gt   vscode extensions  to the same location on the target machine    Works perfectly
