VSCode Extension Download Tool (Marketplace to VSIX)

This tool converts a VSCode Marketplace link into a downloadable VSIX package URL and lets you download it in one click.

You can paste a full Marketplace URL or enter a plain publisher.extension itemName.

Key Features

• Supports both Marketplace URL and itemName input
• Automatically extracts and validates itemName
• One-click VSIX download
• Shows resolved itemName and final VSIX URL for debugging
• Fully frontend implementation without backend APIs

How to Use

1. Paste a Marketplace URL, for example: https://marketplace.visualstudio.com/items?itemName=vscodevim.vim
2. Or enter itemName directly: vscodevim.vim
3. Click Download Extension
4. Your browser starts downloading the VSIX package

Input Rules

• Valid itemName must have exactly two parts: publisher.extension
• In URL mode, the tool reads the itemName query parameter
• Invalid or empty input shows an error and disables download

Typical Use Cases

• Installing VSCode extensions in restricted/offline environments
• Sharing extension packages across machines
• Keeping local VSIX backups for reproducible setups
