View guide →Nerfstudio — the plug-and-play studio for NeRFs and Gaussian splatting: turn photos of a real scene into explorable 3D, with a modular API and viewer, Apache-2.0
Nerfstudio is an open-source ai 3d project by nerfstudio-project (nerfstudio-project/nerfstudio on GitHub). It has 12,083 GitHub stars and 1,681 forks, is released under the Apache-2.0 license, and was last updated on GitHub on 29 July 2025.
Per the README: you need an NVIDIA GPU with CUDA; create the conda env (python 3.8 in the README setup), then install PyTorch with CUDA and tiny-cuda-nn.
pip install nerfstudio, then process your photos/video into a dataset with the ns-process-data tools (COLMAP pose estimation under the hood).
Train a method (Nerfacto is the default workhorse; Splatfacto for Gaussian splatting) and inspect, render and export from the built-in viewer.
Data processing, training, a real-time viewer, camera-path rendering and export in one coherent tool.
First-class methods for both families — Nerfacto for NeRF, Splatfacto for 3D Gaussian splatting.
Components are interpretable and swappable, so new methods plug in — the reason the research community builds on it.
Explore the scene as it trains, set camera paths and export renders without leaving the tool.
The README environment setup.
conda create --name nerfstudio -y python=3.8
conda activate nerfstudio
pip install --upgrade pipCUDA 11.8 build per the README, then the package itself (tiny-cuda-nn is covered in the README dependencies section).
pip install torch==2.1.2+cu118 torchvision==0.16.2+cu118 --extra-index-url https://download.pytorch.org/whl/cu118
pip install nerfstudioThe docs quickstart trains Nerfacto on the classic Blender scene, then on your own captures.

Yes — Apache-2.0 licensed.
An NVIDIA GPU with CUDA installed — the README tested setup is CUDA 11.8 with PyTorch 2.1.2. CPU-only training is not the intended path.
Against the original gaussian-splatting research repo, Nerfstudio is the full studio — data processing, viewer, many methods, exports — rather than a single-method implementation. Against hosted capture apps (Luma, Polycam), it is free, local and export-friendly, at the cost of running the training yourself.
Follow the README: conda env, PyTorch with CUDA, tiny-cuda-nn, pip install nerfstudio — then run the docs quickstart on the Blender scene before your own photos.
