Let’s go through the advantages of uv (github) over pip with the following a few aspects.

Positioning

• pip
  • The default Python package manager, officially recommended
• uv
  • A fast Python package manager and virtual environment tool from Astral (the team behind ruff and rye)

Performance

• pip
  • Pure python implementation
  • Dependency resolution and installation can be slow
  • Downloads and installs wheels sequentially
• uv
  • Written in Rust, heavily optimized
  • Dependency resolutions is 10-100x faster
  • Parallel downloads & extraction, with aggressive caching
  • Reinstalls cached packages in seconds

Virtual Environment Support

• pip
  • Doesn’t support manage environments itself; relies on venv or virtualenv
• uv
  • Built-in environment management: uv venv .
  • Similar to rye, no need for external tools

Dependency Resolution

• pip
  • Has a resolver (since pip 20.x), but relatively slow
  • No native lock file support (requires pip-tools to generate pinned requirements)
• uv
  • High-performance built-in resolver
  • Supports lock files (uv.lock) for reproducible installs
  • Can parse both requirements.txt and pyproject.toml

Cross-Platform Experiences

• pip
  • Behavior may vary depending on OS and environment
• uv
  • Designed for consistent cross-platform behavior

In summary, while pip remains the standard and most widely adopted tool, uv offers a modern, high-performance alternative that simplifies Python package management. It’s still early days for uv, but it’s worth keeping an eye on as the ecosystem matures.
