Open-source alternatives to Networker

A library for working with IP addresses and networks in Go

Mongoose is an embedded networking library providing TCP/IP stacks, web server hosting, and IoT device connectivity. It enables microcontrollers and desktop systems to implement network protocols including HTTP, WebSocket, and MQTT. The project provides a bare-metal TCP/IP stack for environments without a native operating system and includes built-in TLS and ECC encryption to secure network traffic. It features a binary-embedded file system to serve web content directly from the executable and supports over-the-air firmware updates for managing device fleets. Additional capabilities cover as

MagicOnion is a .NET RPC framework used to build type-safe remote procedure call services using shared interfaces for communication between servers and clients. It functions as a binary serialization framework and a distributed service orchestrator, providing a network layer for low-latency streaming and real-time data exchange. The project distinguishes itself through an AOT-compatible network client that uses source generators to support ahead-of-time compilation in restricted runtime environments. It enables bidirectional communication and real-time data streaming, allowing servers and mul

Gmqtt is a flexible, high-performance MQTT broker library that fully implements the MQTT protocol V3.x and V5 in golang

A simple wrapper around libpcap for the Go programming language

httplab is an interactive HTTP mock server, request inspection tool, and response simulator. It functions as a web server designed to capture and analyze incoming HTTP requests and headers in real time for debugging purposes. The tool enables the construction and delivery of custom HTTP responses to simulate various server behaviors. Users can forge specific headers and bodies to test how client applications handle different status codes and payloads, with the ability to save these configurations as response templates for consistent reuse across sessions. The project covers a broad surface o

Alamofire is an HTTP networking library that provides a foundation for managing network requests and responses through a chainable, type-safe interface. It serves as an asynchronous request manager, coordinating concurrent network operations and data streams while maintaining application responsiveness. The library distinguishes itself through a protocol-oriented request adaptation system, which utilizes interceptors to modify or authenticate requests before dispatch. It employs a middleware-driven pipeline to process traffic, handling encoding, authentication, and error recovery in a modular

Reachability.swift is a network connectivity listener and Swift network state wrapper. It monitors real-time changes to network status and tracks whether a device is connected to Wi-Fi or cellular data. The library functions as a network reachability monitor that uses closures and system notifications to trigger callbacks when connectivity changes. It tracks internet connectivity and connection types to allow for network state handling and the adjustment of app content loading based on availability.

Colyseus is a real-time multiplayer game framework for Node.js that provides an authoritative server model, delta-compressed state synchronization, and room-based session orchestration. It is designed to handle the core infrastructure of multiplayer games, including matchmaking, state management, and scalable process distribution across multiple servers. The framework distinguishes itself through its schema-based state definition, which enables automatic serialization and change tracking, combined with a binary WebSocket protocol for low-latency updates. Its matchmaking pipeline routes player

Fortio is a performance testing tool written in Go that generates constant request rates to measure latency histograms and response percentiles. It functions as a network performance benchmarker for analyzing system performance across HTTP and gRPC endpoints, and includes a specialized HTTP echo server for mirroring requests. The project distinguishes itself through a web-based HTTP load testing API used for triggering asynchronous tests and visualizing result data through graphs. It also provides server behavior simulation, allowing the echo server to inject artificial delays and vary respon
