# Flower: A Friendly Federated AI Framework
Website |
Blog |
Docs |
Slack
Flower (`flwr`) is a framework for building federated AI systems. The
design of Flower is based on a few guiding principles:
- **Customizable**: Federated learning systems vary wildly from one use case to
another. Flower allows for a wide range of different configurations depending
on the needs of each individual use case.
- **Extendable**: Flower originated from a research project at the University of
Oxford, so it was built with AI research in mind. Many components can be
extended and overridden to build new state-of-the-art systems.
- **Framework-agnostic**: Different machine learning frameworks have different
strengths. Flower can be used with any machine learning framework, for
example, [PyTorch](https://pytorch.org), [TensorFlow](https://tensorflow.org), [Hugging Face Transformers](https://huggingface.co/), [PyTorch Lightning](https://pytorchlightning.ai/), [scikit-learn](https://scikit-learn.org/), [JAX](https://jax.readthedocs.io/), [TFLite](https://tensorflow.org/lite/), [MONAI](https://docs.monai.io/en/latest/index.html), [fastai](https://www.fast.ai/), [MLX](https://ml-explore.github.io/mlx/build/html/index.html), [XGBoost](https://xgboost.readthedocs.io/en/stable/), [CatBoost](https://catboost.ai/), [LeRobot](https://github.com/huggingface/lerobot) for federated robots, [Pandas](https://pandas.pydata.org/) for federated analytics, or even raw [NumPy](https://numpy.org/)
for users who enjoy computing gradients by hand.
- **Understandable**: Flower is written with maintainability in mind. The
community is encouraged to both read and contribute to the codebase.
