## Cloudsmith: a stable **pyx alternative** for private Python and uv package registries

[Talk to us about migrating from pyx](/book-a-migration-consultation)

WHY CHOOSE CLOUDSMITH?

## Four reasons teams are migrating from pyx to Cloudsmith

Since Astral announced it was winding down its hosted version of the pyx private Python package registry, customers need another registry for private Python packages. Cloudsmith is a full-featured pyx alternative that keeps your uv workflow running and adds supply chain security, policy enforcement, and 30+ package formats.

### A stable home for private Python registries

Cloudsmith knows Python. It’s been one of the most popular formats since we launched our artifact management platform. We’re known and trusted by the Python community.

### Keep your uv workflow, plus pip and Poetry

Cloudsmith speaks the PEP 503 Simple Repository API, so uv resolves and installs from your Cloudsmith index. Developers and pipelines that pointed at pyx or PyPI can point at a Cloudsmith repository instead. Any compatible Python package manager, like pip, uv, or Poetry, works against the same repository. With 700+ edge locations worldwide, Cloudsmith is fast.

### One registry for every format, not just Python

Manage your Docker images, Helm charts, npm, Maven packages, ML models, and 30+ other formats in a single repository. 

### Supply chain security and governance built in

Cloudsmith secures the whole software supply chain.

## Frequently asked questions

### What is pyx?

pyx is a Python-native package registry from Astral, the team behind uv and Ruff. It launched in beta in August 2025 as a fast, uv-native home for private packages, with PyPI and PyTorch mirrors and GPU-aware installs.

### What happened to pyx? Is it still available?

The hosted pyx registry is being sunsetted by Astral. 

### What's the best pyx alternative?

Cloudsmith. It serves as a private, uv-compatible Python registry that also proxies PyPI, along with: 30+ package formats, built-in supply chain security & policy enforcement and, Global distribution

### Does uv work with Cloudsmith?

Cloudsmith supports the PEP 503 API that uv speaks, so getting started is straightforward: point uv at your Cloudsmith index URL, authenticate with a token (via an environment variable or netrc), and then resolve and install packages just like you would from PyPI or pyx.

### How do I migrate from pyx to Cloudsmith?

Migrating from pyx to Cloudsmith takes three steps: start by creating a Cloudsmith repository and pointing an upstream at PyPI so packages get indexed and cached, then publish your private packages using uv or twine (or batch-upload them with the Cloudsmith CLI), and finally switch your developer and pipeline index URLs over to Cloudsmith.

### Does Cloudsmith only support Python?

No. Python is one of 30+ formats. You also get Docker, Helm, npm, Maven, NuGet, Debian, Alpine, Cargo, RubyGems, and more, all in one registry, under one access model.

### How does Cloudsmith's pricing compare to pyx?

Cloudsmith's pricing compares favorably in scope: pyx was a paid Python-only registry, whereas Cloudsmith uses usage-based pricing and gives you a registry, security scanning, policy, and distribution together, with a free trial to start. That also means you may be able to consolidate several tools into one platform rather than paying separately for a single-format package store.
