[Larecs🌲](https://github.com/samufi/larecs) is a performance-oriented archetype-based ECS for Mojo🔥, originally based on the Go ECS [Arche](https://github.com/mlange-42/arche).

## Features

- Clean and simple API
- High performance due to archetype-based architecture and extensive use of Mojo’s compile-time programming tools
- Support for SIMD computing via a [`vectorize`](https://docs.modular.com/mojo/stdlib/algorithm/functional/vectorize/)-like syntax
- Compile-time checks thanks to usage of parameters
- Native support for [resources](https://mlange-42.github.io/arche/guide/resources/)
- Tested and benchmarked
- No external dependencies
- More features coming soon…
