Contributing

Casbin is an open-source authorization library with implementations in many languages. We welcome contributors in any of the supported languages.

The project splits into two main areas:

• Core and language ports — Implementing Casbin’s core and ecosystem in Go, Java, Node.js, PHP, Python, .NET, C++, Rust, and others.
