  <i>Installing <a href="https://trio.readthedocs.io/">Trio</a>'s dependencies with a warm cache.</i>
</p>

## Highlights

- A single tool to replace `pip`, `pip-tools`, `pipx`, `poetry`, `pyenv`, `twine`, `virtualenv`, and
  more.
- [10-100x faster](https://github.com/astral-sh/uv/blob/main/BENCHMARKS.md) than `pip`.
- Provides [comprehensive project management](https://github.com/astral-sh/uv/blob/0.13.4/README.md#projects), with a
  [universal lockfile](https://docs.astral.sh/uv/concepts/projects/layout#the-lockfile).
- [Runs scripts](https://github.com/astral-sh/uv/blob/0.13.4/README.md#scripts), with support for
  [inline dependency metadata](https://docs.astral.sh/uv/guides/scripts#declaring-script-dependencies).
- [Installs and manages](https://github.com/astral-sh/uv/blob/0.13.4/README.md#python-versions) Python versions.
- [Runs and installs](https://github.com/astral-sh/uv/blob/0.13.4/README.md#tools) tools published as Python packages.
- Includes a [pip-compatible interface](https://github.com/astral-sh/uv/blob/0.13.4/README.md#the-pip-interface) for a performance boost with a familiar
  CLI.
- Supports Cargo-style [workspaces](https://docs.astral.sh/uv/concepts/projects/workspaces) for
  scalable projects.
- Disk-space efficient, with a [global cache](https://docs.astral.sh/uv/concepts/cache) for
  dependency deduplication.
- Installable without Rust or Python via `curl` or `pip`.
- Supports macOS, Linux, and Windows.

uv is backed by [Astral](https://astral.sh), the creators of
[Ruff](https://github.com/astral-sh/ruff) and [ty](https://github.com/astral-sh/ty).

## Installation

Install uv with our standalone installers:

```bash
# On macOS and Linux.
curl -LsSf https://astral.sh/uv/install.sh | sh
```

```bash
# On Windows.
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
```

Or, from [PyPI](https://pypi.org/project/uv/):

```bash
# With pip.
pip install uv
```

```bash
# Or pipx.
pipx install uv
```

If installed via the standalone installer, uv can update itself to the latest version:

```bash
uv self update
```

See the [installation documentation](https://docs.astral.sh/uv/getting-started/installation/) for
details and alternative installation methods.

## Documentation

uv's documentation is available at [docs.astral.sh/uv](https://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`:

```console
$ uv init example
Initialized project `example` at `/home/user/example`

$ cd example

$ uv add ruff
Creating virtual environment at: .venv
Resolved 2 packages in 170ms
   Built example @ file:///home/user/example
Prepared 2 packages in 627ms
Installed 2 packages in 1ms
 + example==0.1.0 (from file:///home/user/example)
 + ruff==0.5.0

$ uv run ruff check
All checks passed!

$ uv lock
Resolved 2 packages in 0.33ms

$ uv sync
Resolved 2 packages in 0.70ms
Checked 1 package in 0.02ms
```

See the [project documentation](https://docs.astral.sh/uv/guides/projects/) to get started.

uv also supports building and publishing projects, even if they're not managed with uv. See the
[publish guide](https://docs.astral.sh/uv/guides/publish/) to learn more.

### Scripts

uv manages dependencies and environments for single-file scripts.

Create a new script and add inline metadata declaring its dependencies:

```console
$ echo 'import requests; print(requests.get("https://astral.sh"))' > example.py

$ uv add --script example.py requests
Updated `example.py`
```

Then, run the script in an isolated virtual environment:

```console
$ uv run example.py
Reading inline script metadata from: example.py
Installed 5 packages in 12ms
<Response [200]>
```

See the [scripts documentation](https://docs.astral.sh/uv/guides/scripts/) 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`):

```console
$ uvx pycowsay 'hello world!'
Resolved 1 package in 167ms
Installed 1 package in 9ms
 + pycowsay==0.0.0.2
  """

  ------------
< hello world! >
  ------------
   \   ^__^
    \  (oo)\_______
       (__)\       )\/\
           ||----w |
           ||     ||
```

Install a tool with `uv tool install`:

```console
$ uv tool install ruff
Resolved 1 package in 6ms
Installed 1 package in 2ms
 + ruff==0.5.0
Installed 1 executable: ruff

$ ruff --version
ruff 0.5.0
```

See the [tools documentation](https://docs.astral.sh/uv/guides/tools/) to get started.

### Python versions

uv installs Python and allows quickly switching between versions.

Install multiple Python versions:

```console
$ uv python install 3.12 3.13 3.14
Installed 3 versions in 972ms
 + cpython-3.12.12-macos-aarch64-none (python3.12)
 + cpython-3.13.9-macos-aarch64-none (python3.13)
 + cpython-3.14.0-macos-aarch64-none (python3.14)

```

Download Python versions as needed:

```console
$ uv venv --python 3.12.0
Using Python 3.12.0
Creating virtual environment at: .venv
Activate with: source .venv/bin/activate

$ uv run --python pypy@3.8 -- python --version
Python 3.8.16 (a9dbdca6fc3286b0addd2240f11d97d8e8de187a, Dec 29 2022, 11:45:30)
[PyPy 7.3.11 with GCC Apple LLVM 13.1.6 (clang-1316.0.21.2.5)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>>>
```

Use a specific Python version in the current directory:

```console
$ uv python pin 3.11
Pinned `.python-version` to `3.11`
```

See the [Python installation documentation](https://docs.astral.sh/uv/guides/install-python/) 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.

Compile requirements into a platform-independent requirements file:

```console
$ uv pip compile requirements.in \
   --universal \
   --output-file requirements.txt
Resolved 43 packages in 12ms
```

Create a virtual environment:

```console
$ uv venv
Using Python 3.12.3
Creating virtual environment at: .venv
Activate with: source .venv/bin/activate
```

Install the locked requirements:

```console
$ uv pip sync requirements.txt
Resolved 43 packages in 11ms
Installed 43 packages in 208ms
 + babel==2.15.0
 + black==24.4.2
 + certifi==2024.7.4
 ...
```

See the [pip interface documentation](https://docs.astral.sh/uv/pip/index/) to get started.

It's pronounced as "you - vee" ([`/juː viː/`](https://en.wikipedia.org/wiki/Help:IPA/English#Key))

#### How should I stylize uv?

Just "uv", please. See the [style guide](https://github.com/astral-sh/uv/blob/0.13.4/STYLE.md#styling-uv) for details.

#### What platforms does uv support?

See uv's [platform support](https://docs.astral.sh/uv/reference/platforms/) document.

#### Is uv ready for production?

Yes, uv is stable and widely used in production. See uv's
[versioning policy](https://docs.astral.sh/uv/reference/versioning/) document for details.

## Acknowledgements

uv's dependency resolver uses [PubGrub](https://github.com/pubgrub-rs/pubgrub) under the hood. We're
grateful to the PubGrub maintainers, especially [Jacob Finkelman](https://github.com/Eh2406), for
their support.

uv's Git implementation is based on [Cargo](https://github.com/rust-lang/cargo).

Some of uv's optimizations are inspired by the great work we've seen in [pnpm](https://pnpm.io/),
[Orogene](https://github.com/orogene/orogene), and [Bun](https://github.com/oven-sh/bun). We've also
learned a lot from Nathaniel J. Smith's [Posy](https://github.com/njsmith/posy) and adapted its
[trampoline](https://github.com/njsmith/posy/tree/main/src/trampolines/windows-trampolines/posy-trampoline)
for Windows support.
