About ZipStream

What is ZipStream?

ZipStream is an open-source service for creating zip files on-the-fly from multiple web URLs. Instead of downloading files to a server first and then zipping them, ZipStream streams files directly from their source URLs into a zip archive that's delivered to your browser.

This approach has several advantages:

  • Low Memory - Files are never fully stored on the server
  • Fast Response - Download starts immediately, no processing delay
  • High Scalability - Handle many concurrent requests efficiently

How It Works

1 You send a JSON descriptor with file URLs
→
2 ZipStream fetches files from source URLs
→
3 Files stream directly into a zip archive
→
4 Zip streams to your browser in real-time
