Open-source alternatives to RestKit

MJExtension is a JSON serialization library and model mapping framework used to convert data between JSON strings and structured model objects. It functions as an object data mapper that handles the encoding and decoding of complex object hierarchies for network transmission and storage. The framework is a non-intrusive data mapper that uses reflection and runtime inspection to map raw data strings to application objects. This approach allows for data transformation without requiring base class inheritance, decorators, or extensions to the underlying model classes. The system supports recurs

go-restful is a framework for building RESTful web services in Go. It functions as a toolkit for managing API endpoints, providing a request router that maps incoming HTTP requests to handler functions using path parameters and custom URL patterns. The framework includes a data conversion layer that transforms Go structures into JSON or XML formats for request and response bodies. It also provides a system for organizing related web services into containers to manage endpoint prefixing and shared configuration. The project covers request lifecycle management through middleware filters for va

Retrofit is a type-safe HTTP client that simplifies network communication by allowing developers to define API endpoints as interface methods. By using annotation-driven request mapping, it automatically translates these interface definitions into structured HTTP requests, ensuring consistent data structures and reducing manual configuration when interacting with remote web services. The project distinguishes itself through a highly modular architecture that separates network transport from data handling. It utilizes dynamic proxy generation to process method calls at runtime and offers a plu

Restangular is a REST client and resource mapper for AngularJS applications. It provides a suite of tools for mapping API endpoints to local objects and collections, facilitating frontend CRUD implementation through standard HTTP methods. The project distinguishes itself through an async data binding system that links user interface elements to server-side objects, ensuring automatic updates upon request completion. It also features a programmable request interceptor pipeline for modifying headers and transforming responses, as well as a JSONP request handler to bypass same-origin policy rest

cpr is a C++ networking library that provides a high-level HTTP request client. It functions as a wrapper around libcurl to simplify the process of sending and receiving data from web servers, specifically managing GET and POST calls and multipart form uploads. The library provides both synchronous and asynchronous execution models, allowing network requests to run on background threads to prevent application freezing. It integrates with the C++ Standard Library to map low-level pointers to standard strings and containers, utilizing RAII for automatic resource management. The project covers

Hazelcast is a distributed data platform that combines an in-memory data grid with a stream processing engine to support real-time analytics and event-driven applications. It functions as a partitioned, distributed key-value store that replicates data across cluster nodes to provide low-latency access and high availability. The platform also serves as a distributed SQL query engine, allowing users to execute standard SQL statements against both in-memory datasets and external data sources. What distinguishes Hazelcast is its use of a distributed consensus subsystem to maintain strongly consis

Rest-assured is a Java-based REST API testing framework and HTTP client library designed for automating web service tests. It provides a fluent domain-specific language and assertion library to send HTTP requests and validate response metadata, including status codes, headers, cookies, and bodies. The framework is distinguished by a method-chaining DSL that creates readable specifications for API interactions. It features a filter-based request interception pipeline, object-mapping serialization for converting Java objects to JSON or XML, and a path-based parsing system to isolate specific fi

This is an asynchronous HTTP client for Android that simplifies network requests by wrapping Apache HttpClient. It provides a callback-based networking library for fetching remote data and communicating with servers without blocking the user interface. The project includes a multipart HTTP uploader for sending binary files and large data payloads, as well as a JSON parser to convert raw response text into structured data objects. It features a session manager that persists cookies in local application preferences to maintain state across multiple requests. Additional capabilities include aut

foursquare iOS networking library

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

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

Package for downloading things from a string URL using a variety of protocols.

Simple mDNS client/server library in Golang

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

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
