iodine - HTTP / WebSockets Server for Ruby with Pub/Sub support

Django Channels HTTP/WebSocket server

This project is a set of configuration guides and instructional tutorials for setting up Nginx as a web server and reverse proxy. It provides practical examples for hosting static files and directing network traffic to backend servers. The materials cover the implementation of load balancing using weighted round-robin strategies to distribute traffic across server clusters. It also provides guidance on configuring reverse proxies to manage request flow and secure application access. The documentation includes instructions for routing requests by URL path to host multiple applications on a si

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

gRPC is a language-agnostic remote procedure call framework designed for high-performance communication between distributed services. It utilizes a structured interface definition language to generate consistent client stubs and server skeletons, enabling applications to invoke methods on remote servers as if they were local objects. By leveraging the HTTP/2 transport layer, the framework supports efficient binary serialization and multiplexed data exchange across diverse programming environments. The framework distinguishes itself through its support for flexible communication patterns, incl

Lightweight embeddable web server written in pure C# with few dependencies to 3rd-party libraries.

NanoHTTPD is a lightweight, embeddable HTTP server for Java applications. It allows developers to integrate web server capabilities directly into a Java project to handle incoming requests without requiring a standalone installation. The project provides specialized implementations for an HTTPS web server, a WebSocket server for bidirectional real-time communication, and a static file web server. These capabilities enable secure network traffic through SSL certificates and the delivery of local files with automatic MIME type detection. The server includes systems for request routing and hand

Hypercorn is an ASGI and WSGI Server based on Hyper libraries and inspired by Gunicorn.

Puma is a concurrent HTTP server for Ruby applications that implements the Rack interface. It operates as a clustered web server, using a combination of worker processes and threads to handle multiple simultaneous web connections via TCP ports or UNIX domain sockets. The server features a master-worker process model that utilizes multiple CPU cores and employs copy-on-write preloading to reduce memory usage. It supports zero-downtime restarts through socket-handover capabilities, allowing application updates without dropping pending network requests. The project includes a token-authenticate
