Uv
uv is a high-performance Python package manager and project build tool designed to handle dependency resolution, virtual environment orchestration, and Python interpreter management. It functions as a comprehensive workspace orchestrator, enabling developers to manage complex, multi-package repositories and ensure reproducible builds across different platforms.
The tool distinguishes itself through its use of a global, content-addressable cache and hard-link-based environment provisioning, which allow for near-instant environment creation and minimal disk usage. It employs a high-performance solver to satisfy complex dependency graphs and supports ephemeral script execution, allowing users to run standalone Python scripts with ad-hoc dependencies without manual setup.
Beyond core package management, the project provides a unified command-line interface that integrates with CI/CD pipelines and supports common workflows like building distributions and managing private package indexes. It maintains compatibility with standard tools, offering a drop-in replacement for common environment and package management commands.
Comprehensive documentation is available on the project website, covering installation guides, command references, and configuration settings for various development and production environments.
