Package Managers
Overview
Upload, download, and manage all your packages through Fly. All your dependencies are cached and managed through Fly, providing faster downloads and unified dependency management.
Three ways to upload and download artifacts with Fly:
Locally with your Fly App - Toggle your package manager to active, and you’re ready to go. No tokens, no configuration files.
Release with CI - Add the Fly action to your GitHub Actions workflow. Your CI automatically uploads and downloads from Fly.
Authentication with Tokens - Generate a token and configure your package manager. For Kubernetes, external systems, or environments without the Fly App.

Public Registry Proxying
JFrog Fly proxies public registries, providing:
- Speed - Cached public dependencies download faster
- Reliability - Available even if public registry is down (for cached dependencies)
- Unified Access - Single registry for both your private packages and public dependencies
When you request a package, JFrog Fly checks your private artifacts first, then fetches from the public registry if needed and caches it for future use.
