Since 2025, Microsoft has closed the direct .vsix file download portal for the VS Code Marketplace, causing significant inconvenience for developers working in enterprise intranets or offline environments. This article details the 3 known methods for offline downloading of VS Code extensions to help you find the most suitable solution.
Method 1: VS Code Built-in Download (Online Environment)
If your device has internet access and VS Code is installed, this is the simplest and most direct method.
Steps
- Open VS Code and click the "Extensions" icon in the left activity bar
- Enter the extension name in the search box (e.g., "Python")
- Find the target extension and right-click on it
- Select the "Download VSIX" option
- Choose a save location; the .vsix file will be downloaded locally
✅ Pros: Simple and direct, no third-party tools needed, official native support
❌ Cons: Requires VS Code installation, one extension at a time, no historical versions
Best for: Temporarily downloading a small number of extensions
Method 2: Manual URL Construction
VS Code extension download links follow a fixed format. By obtaining the publisher, name, and version of an extension, you can manually construct the download address.
URL Format
How to Get Parameters
- Visit VS Code Marketplace
- Search for and enter the target extension detail page
- Find the identifier in the "Installation" section on the right (format: publisher.extension)
- Find the version number in the "Version" section
Platform Parameter (Optional)
Some extensions are platform-specific. You can specify the platform by adding ?targetPlatform={platform} to the URL:
win32-x64- Windows 64-bitdarwin-arm64- macOS Apple Siliconlinux-x64- Linux 64-bit
✅ Pros: No tools needed, can download historical versions
❌ Cons: Error-prone, tedious, no batch download, requires manual version lookup
Best for: Downloading a specific version of a single extension
Method 3: Extensions Toolkit (Recommended)
Extensions Toolkit is a free tool specifically developed to solve extension download problems in enterprise intranets and offline environments, supporting search, batch download, and historical version selection.
Core Features
Extension Search
Search directly by extension name without memorizing complex identifiers, supporting fuzzy matching.
URL Parsing
Paste the Marketplace extension detail page URL to automatically parse and generate download links.
Historical Versions
Support selecting any historical version for download, solving compatibility issues.
Multi-Platform Support
Automatically identifies current system, supporting Windows, macOS, and Linux downloads.
Batch Download
Shopping cart feature allows adding multiple extensions to the download list and packaging them with one click.
ZIP Packaging
Package multiple extensions into a ZIP file for easy transfer and batch installation.
How to Use
Option A: Extension Search
- Visit Extensions Toolkit - VS Code
- Enter the extension name in the search box (e.g., "Python")
- Click the extension card in the search results
- Select version and platform, then click download
Option B: URL Parsing
- Find the target extension on Marketplace and copy the detail page URL
- Visit URL Tool
- Paste the URL and click "Generate Download Link"
- Select version and platform, download the .vsix file
How It Works
Extensions Toolkit implements extension downloads through the following steps:
- Calls the VS Code Marketplace official API based on user input (extension name or URL) to get extension information
- Parses extension information to get all available versions and supported platforms
- Constructs direct download links according to the URL rules introduced in Method 2
- Provides .vsix files to users through streaming forwarding
✅ Pros: Most comprehensive features, simplest operation, supports batch download and historical versions, completely free
Best for: Enterprise intranet environments, batch deployment, specific version needs, efficiency-focused developers
Security: Only calls official API to construct download links, does not store or modify extension files

Offline Installation Guide
After downloading the .vsix file, install the extension in an offline environment:
Drag & Drop (Recommended)
Open VS Code and click the "Extensions" icon in the left sidebar
Drag the downloaded .vsix file directly into the Extensions view
Wait for the installation to complete; restart VS Code if prompted
Command Line (Batch)
Open a terminal and navigate to the directory containing .vsix files
Run the installation command
Wait for the installation to complete
Common Commands
# Install single extension
code --install-extension /path/to/extension.vsix
# Batch install (Linux/macOS)
for ext in *.vsix; do code --install-extension "$ext"; done
# Batch install (Windows PowerShell)
Get-ChildItem *.vsix | ForEach-Object { code --install-extension $_.FullName }
FAQ
Q: How to determine which platforms an extension supports?
In Extensions Toolkit search results, if the extension card shows a platform count in the upper left (e.g., "Supports 5 platforms"), the extension is platform-specific; if not shown, it's a universal extension that works on all platforms.
Q: How to update extensions in an offline environment?
You need to re-download the new version's .vsix file in an online environment, then install it in the offline environment via "Install from VSIX" to overwrite the old version. Extensions Toolkit supports viewing version release dates to help you select the latest version.
Q: Is Extensions Toolkit safe?
Extensions Toolkit only acts as a download link generator, not storing or modifying extension files. All .vsix files are downloaded directly from Microsoft's official servers, identical to files downloaded through VS Code's built-in functionality.
Q: What if the downloaded extension fails to install?
Please check: 1) Whether the extension supports the current platform; 2) If the VS Code version meets the extension requirements; 3) If the correct architecture version was downloaded (e.g., ARM64 vs x64). You can view detailed compatibility information in Extensions Toolkit.
Conclusion
Microsoft's closure of the official VSIX download portal has indeed brought inconvenience to offline development, but through the methods above, you can still efficiently obtain and manage VS Code extensions.
For occasionally downloading individual extensions, Method 1 and Method 2 are sufficient; but for enterprise intranet batch deployment, specific version requirements, or efficiency-focused scenarios, Extensions Toolkit is the best choice.
