## What it is
Robyn is a high-performance async Python web framework with a Rust runtime, offering routing, middleware, WebSockets, templating, authentication, and OpenAPI support. It includes a CLI for scaffolding projects with optional database and Docker setups.

## Use cases
- build a fast async REST API in Python
- serve websockets for real-time notifications
- scaffold a web app with database and Docker setup
- replace Flask with a more performant framework
- generate OpenAPI docs for a Python backend
- run a multi-core scaled Python web server

## When to choose
- you want Python ergonomics with Rust-level HTTP performance
- you need async, WebSockets, and multi-core scaling out of the box
- you want quick project scaffolding with CLI and Docker support

## When to avoid
- you need a very mature ecosystem with extensive third-party plugins
- your team cannot handle a Rust extension dependency in the build
- you rely on Django-style batteries-included features like ORM and admin

## Facets
- artifact type: framework
- maturity: active
- function: web-framework, http-server, routing, middleware, websocket, templating, cli
- domain: web-development, backend, apis, developer-tools
- platform: python, rust, cross-platform
- tags: async, rust-runtime, flask-alternative, high-performance, openapi, project-scaffolding, docker
