Granian is a Rust-based HTTP server written specifically to serve Python web applications. It supports the three major Python gateway interfaces—ASGI for asynchronous apps, WSGI for synchronous apps, and RSGI for async requests—while also handling HTTP/1.1, HTTP/2, and WebSocket connections through automatic protocol negotiation. Architecturally, Granian uses a multiprocess worker model that isolates requests across CPU cores and provides configurable threadpool-limited concurrency to control backpressure per worker. It includes built-in Prometheus metrics exposition for connection counts and
Super lightweight async HTTP server library in pure Swift runs in iOS / MacOS / Linux
Gunicorn is a production-grade WSGI HTTP server designed for deploying Python web applications. It functions as a process manager that utilizes a pre-fork worker model, where a master process initializes the application and spawns multiple child processes to handle incoming requests in parallel. This architecture ensures high performance and stability by isolating application execution within persistent worker processes. The server distinguishes itself through its flexible concurrency models and robust process lifecycle management. It supports interchangeable worker types, including synchrono
