# 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.

### Proxied Public Registries

| **Docker** | Docker, Docker Buildx, Podman | https://registry-1.docker.io (DockerHub) |
| **Helm** | Helm CLI | https://registry-1.docker.io (DockerHub) |
| **npm** | npm, pnpm | https://registry.npmjs.org |
| **PyPI** | pip, Pipenv, Poetry, Twine | https://files.pythonhosted.org (PyPI) |
| **Go** | Go | https://proxy.golang.org |
| **.NET** | dotnet CLI, NuGet CLI | https://www.nuget.org |
| **Maven** | Maven | https://repo1.maven.org/maven2 (Maven Central) |
| **Gradle** | Gradle | https://repo1.maven.org/maven2 (Maven Central) |
