The next step in Python packaging
About
- pyx is a Python-native package registry built by the uv team, making installs from PyPI, PyTorch, and private sources up to 10x faster
- Goes beyond the scope of a traditional package registry, offering speed, security, and GPU awareness, and supports both internal packages and public sources such as PyPI and PyTorch
- Strengthens security and compliance with dedicated index URLs that can filter by criteria such as package popularity, creation date, and vulnerability status
- Supports the latest Python-specific standards and integrates directly with uv, so authentication and usage work without configuration
- Solves major enterprise problems such as duplicate builds within teams, the difficulty of installing PyTorch/CUDA, broken builds, and inconvenient authentication through server-client integration
- GPU awareness provides prebuilt versions of PyTorch, vLLM, FlashAttention, DeepSpeed, and more that match your hardware, with consistent metadata and optimal configuration
- Delivers far better performance than other private registries through optimized artifacts and a uv-native metadata API
