uWSGI application server container

Waitress - A WSGI server for Python 3

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

This project is a production-ready Docker deployment template for FastAPI applications. It provides a standardized Python web application container that integrates Uvicorn as the ASGI server and Gunicorn as the process manager to handle concurrent requests across multiple CPU cores. The configuration enables performance tuning by adjusting worker processes and server settings based on available CPU resources. It utilizes a multi-stage Docker build to separate build dependencies from the final runtime image. The system covers containerized web hosting, including support for environment-variab

Channels is an extension for the Django web framework that adds native support for WebSockets, background tasks, and long-running connections alongside standard HTTP requests. It provides a channel layer abstraction for passing messages between different parts of a Django application across processes, along with a protocol router that inspects incoming connections and dispatches them to the correct handler for HTTP, WebSocket, or custom protocols. The project introduces an async consumer abstraction that wraps protocol-specific handling into a single callable, and a background worker pool tha

Swifter is a lightweight HTTP server engine and routing system written in the Swift programming language. It functions as a web server capable of handling network requests and delivering responses such as HTML and plain text. The project provides a Swift WebSocket server for establishing bidirectional real-time communication channels to exchange text and binary data. It also includes a static file server that maps URL paths to local directories for direct file system access. The engine manages HTTP request routing by mapping specific URL paths to handler functions for delivering dynamic cont

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

Kitura is a server-side web framework for building HTTP services and web applications using the Swift programming language. It functions as an HTTP server that handles incoming requests, routes traffic, and serves responses. The framework serves as a Codable REST API framework, enabling the encoding and decoding of native Swift data types for web service communication. It also provides a FastCGI web interface to connect Swift applications to external web servers for improved scalability. The system includes capabilities for secure web communication through SSL/TLS network encryption, server-

Swift HTTP server using the pre-fork worker model

A very fast & simple Ruby web server

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

Evented I/O streams for Swift

A High Performance HTTP Server for Ruby

A lightweight, async HTTP client

Asynchronous HTTP server in common lisp

Perfect is a server-side Swift framework designed for building high-performance web applications, REST APIs, and backend services. It provides an asynchronous HTTP server that handles web traffic through an event loop, alongside a web template engine for generating dynamic HTML pages. The project includes a WebSocket communication library for implementing bidirectional, real-time data exchange between clients and servers. It also provides a database connector to establish connections and exchange data between Swift applications and external database stores. The framework's capabilities cover

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
