vsix-bridge-cli

Sync VS Code extensions to fork IDEs (Cursor, Antigravity, Windsurf) by downloading compatible versions from the official Microsoft Marketplace.

Why?

VS Code forks often use OpenVSIX or custom registries that may:

• Lag behind official Microsoft Marketplace updates
• Miss extensions entirely
• Contain poorly vetted packages

vsix-bridge-cli uses your local VS Code installation as the source of truth, downloads the exact compatible versions, and installs them into fork IDEs.

Installation

npm install -g vsix-bridge-cli

Usage

Detect installed IDEs

vsix-bridge detect

Shows all detected IDEs with their VS Code engine versions and CLI availability.

Sync extensions

vsix-bridge sync                    # Sync to all detected IDEs
vsix-bridge sync --to cursor        # Sync to Cursor only
vsix-bridge sync --to cursor --to windsurf  # Sync to multiple IDEs

Downloads compatible VSIX files from Microsoft Marketplace to ~/.cache/vsix-bridge/<ide>/.

View status

vsix-bridge status                  # Compare VS Code with a fork
vsix-bridge status --to cursor      # Compare with Cursor specifically

Shows:

• Extensions in VS Code but not in fork
• Extensions in fork but not in VS Code
• Version differences
• Disabled state differences

Install extensions

vsix-bridge install --to cursor     # Install synced extensions
vsix-bridge install --dry-run       # Preview without making changes

| Flag | Description | | ----------------- | --------------------------------------------------- | | --sync-removals | Uninstall extensions in fork that aren't in VS Code | | --dry-run | Show what would be done without doing it |
