Granian is a Rust-based HTTP server for Python applications built on Hyper and Tokio, serving ASGI, RSGI, and WSGI apps. It supports HTTP/1, HTTP/2, HTTPS/mTLS, websockets, and static file serving as a single high-performance dependency.

Use cases

• serve an ASGI FastAPI app with a fast production server
• replace gunicorn + uvicorn with a single dependency
• serve a WSGI Flask/Django app over HTTP/2
• run a Python websocket server with high concurrency
• serve static files directly from a Python web app
• benchmark Python web server throughput

When to choose

• you want one modern dependency to serve both ASGI and WSGI applications
• you need the most performant way to serve Python apps under HTTP/2
• you need great websocket concurrency and throughput
• you want a single package with wheels for several platforms

When to avoid

• you need a pure Python solution
• you need advanced debugging features
• your app relies on trio or gevent
• you depend on ASGI extensions not yet implemented
