Setup script in the repo

The maintainers included tools/install_gdrcopy.sh. Run it from the cloned folder after reading it.

bash tools/install_gdrcopy.sh

Also: tools/install_snapshot_runtime.sh, tools/install_torchcodec_rocm.sh, tools/install_triton_from_source.sh, tools/setup_deepgemm_pythons.sh

Will it work on my device?

Yes, it runs on Windows

You'll build it yourself with Python, C/C++ compiler, CMake.

4 steps on Windows

Download setup.ps1

Then run powershell -ExecutionPolicy Bypass -File .\setup.ps1. It stops at the first error and is safe to run again. Servers and tests aren't started; it lists them at the end. Read it first.

Clone the repository

Needs Git: winget install Git.Git

git clone https://github.com/vllm-project/vllm.git
cd vllm

Install the required runtimes

Python >=3.11,<3.15, C/C++ compiler, CMake 3.26

winget install astral-sh.uv
winget install Microsoft.VisualStudio.2022.BuildTools  # then add the "Desktop development with C++" workload
winget install Kitware.CMake

Install dependencies

uv sync
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build

Run the tests
```
uv run pytest
```

From the README: Getting Started

Install vLLM with uv (recommended) or pip:

uv pip install vllm
vllm download-kernels  # precompiled kernels for faster startup

Or build from source for development.

Good to know

Native projects often need extra system libraries. If the build stops with a missing package, check the maintainers' build guide (see Start here).
The README mentions NVIDIA CUDA. Check its hardware section: some features (or all of them) may need an NVIDIA GPU.
Has AGENTS.md — instructions for coding agents. You can open Claude Code (or another agent) in the cloned folder and ask it to do the setup for you.
Nested projects: benchmarks/kernels/requirements.txt, benchmarks/multi_turn/requirements.txt, examples/features/structured_outputs/pyproject.toml, rust/Cargo.toml and 11 more
