UV is a fast, modern Python package manager developed by Astral. It is designed to be a drop-in replacement for tools like pip, pip-tools, and even parts of virtualenv, with a focus on speed and modern features.

🚀 Key Features of UV:

1. Blazing Fast:

   • UV is written in Rust, making it significantly faster than traditional Python tools. It can resolve and install packages faster than pip.

2. Unified Tooling:

   • UV combines the functionality of:

     • pip (installing packages)

     • pip-tools (resolving dependencies)

     • virtualenv (creating isolated environments)

     • venv (environment management)

3. Deterministic Resolution:

   • UV uses lockfiles to ensure consistent and reproducible builds.

4. PEP Support:

   • Supports PEP 508, PEP 610, and other modern Python packaging standards.

5. Cross-platform:

   • Works on Linux, macOS, and Windows.

🔧 Common Commands

1. Install a package

uv pip install requests

2. Create a virtual environment

uv venv

3. Activate virtual environment

• On macOS/Linux:

  source .venv/bin/activate
  

• On Windows:

  .venv\Scripts\activate
  

4. Lock dependencies (like pip-compile)

uv pip compile requirements.in

5. Sync dependencies from a lockfile

uv pip sync requirements.lock
