# uv
An extremely fast Python package and project manager, written in Rust.
 Installing Trio 's dependencies with a warm cache. 
## Highlights
- A single tool to replace `pip`, `pip-tools`, `pipx`, `poetry`, `pyenv`, `twine`, `virtualenv`, and
 more.
- 10-100x faster than `pip`.
- Provides comprehensive project management, with a
 universal lockfile.
- Runs scripts, with support for
 inline dependency metadata.
- Installs and manages Python versions.
- Runs and installs tools published as Python packages.
- Includes a pip-compatible interface for a performance boost with a familiar
 CLI.
- Supports Cargo-style workspaces for
 scalable projects.
- Disk-space efficient, with a global cache for
 dependency deduplication.
- Installable without Rust or Python via `curl` or `pip`.
- Supports macOS, Linux, and Windows.
uv is backed by Astral, the creators of

## Installation
Install uv with our standalone installers:
 [code] 
 [code] 
Or, from PyPI:
 [code] 
 [code] 
If installed via the standalone installer, uv can update itself to the latest version:
 [code] 
See the installation documentation for
details and alternative installation methods.
## Documentation
uv's documentation is available at docs.astral.sh/uv.
Additionally, the command line reference documentation can be viewed with `uv help`.
## Features
### Projects
uv manages project dependencies and environments, with support for lockfiles, workspaces, and more,
similar to `rye` or `poetry`:
 [code] 
See the project documentation to get started.
uv also supports building and publishing projects, even if they're not managed with uv. See the
publish guide to learn more.
### Scripts
uv manages dependencies and environments for single-file scripts.
Create a new script and add inline metadata declaring its dependencies:
 [code] 
Then, run the script in an isolated virtual environment:
 [code] 
See the scripts documentation to get started.
### Tools
uv executes and installs command-line tools provided by Python packages, similar to `pipx`.
Run a tool in an ephemeral environment using `uvx` (an alias for `uv tool run`):
 [code] 
Install a tool with `uv tool install`:
 [code] 
See the tools documentation to get started.
### Python versions
uv installs Python and allows quickly switching between versions.
Install multiple Python versions:
 [code] 
Download Python versions as needed:
 [code] 
Use a specific Python version in the current directory:
 [code] 
See the Python installation documentation to get
started.
### The pip interface
uv provides a drop-in replacement for common `pip`, `pip-tools`, and `virtualenv` commands.
uv extends their interfaces with advanced features, such as dependency version overrides,
platform-independent resolutions, reproducible resolutions, alternative resolution strategies, and
more.
Migrate to uv without changing your existing workflows — and experience a 10-100x speedup — with the
`uv pip` interface.
