# 🚀 Wingfoil
Wingfoil is a **blazingly fast**, highly scalable [stream processing framework](https://github.com/wingfoil-io/wingfoil/tree/main/wingfoil/benches/) designed for **latency-critical** use cases such as electronic trading and real-time AI systems.
Wingfoil simplifies receiving, processing and distributing streaming data across your entire stack.

* **Simple and obvious to use**: Define your graph of calculations; Wingfoil manages its execution.
* **Multi-language**: Currently available as a Rust crate and a Python package, with plans to add WASM/JavaScript/TypeScript support.
* **Backtesting**: Replay historical data to backtest and optimise strategies.
