Open-source alternatives to Go Getter

This project is a Go DNS library used for implementing DNS clients and servers. It provides a toolkit for packet exchange, record parsing, and the development of custom nameservers. The library includes a DNS server framework and a zone manager for parsing standard zone files and synchronizing data via zone transfers. It features a dedicated DNSSEC implementation library for generating cryptographic keys and validating signatures, as well as a TLS transport for encrypted connections between clients and servers. The system covers a broad range of capabilities including DNS resolver functional

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

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

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

gopacket is a Go library for live packet capture and multi-layer protocol decoding. It provides a framework for parsing raw network bytes into structured protocol layers, enabling inspection and analysis of network traffic directly from interfaces or packet capture files. The library distinguishes itself through a layered protocol stack that organizes decoders as independent, composable layers, and an interface-based decoder registry that supports extensible custom protocol development. It offers zero-copy packet decoding for high-throughput parsing, stream-based TCP reassembly to reconstruct
