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

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

🚀Gev is a lightweight, fast non-blocking TCP network library / websocket server based on Reactor mode. Support custom protocols to quickly and easily build high-performance servers.

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

This project is a Go library and framework for implementing the SSH protocol. It provides a toolkit for building custom SSH servers, managing encrypted connections, and handling remote command execution. The implementation focuses on flexible session management through callback-based handling and a pluggable authentication system that supports passwords, public keys, and certificates. It includes mechanisms for secure network tunneling, including local and reverse port forwarding for TCP and Unix domain socket traffic. The library covers a broad range of protocol capabilities, including cryp
