Granian: a Rust HTTP server for Python applications
summary
Granian is a Rust HTTP server for Python applications that uses Rust + Tokio + hyper and pyo3 to offload protocol handling from Python, providing SSL termination, HTTP/2 and websockets while serving supports WSGI ASGI RSGI apps. Benchmarks claim 5.7× to 47× throughput vs plain Uvicorn and about 80% higher websocket concurrency on a single process, with lower CPU and ~10% higher RAM; framework-facing RSGI yields 28x static files speed in one Emmett test. Early releases had baggage; use 0.4.2.
