Robyn is a high-performance asynchronous web framework and server for Python that utilizes a Rust-powered runtime to execute code. It functions as an asynchronous Python web server designed to handle many concurrent requests efficiently through a multithreaded execution model.
The project includes specialized capabilities for AI agent request routing, managing communication between agents and external tools. It also serves as a WebSocket communication server, maintaining persistent bidirectional channels for real-time data exchange.
The framework covers a broad range of web infrastructure, including dynamic URL mapping, middleware execution pipelines, and the ability to stream response data. It provides tools for the development lifecycle such as automatic code reloading and the generation of machine-readable API specifications. Additional utility is provided through static file serving and the application of cross-origin resource sharing policies.
