Open-source alternatives to Nugget

flashheart is built on http-transport to provide everything you need to build HTTP-based services with confidence.

node-fetch is a lightweight HTTP client library that implements the browser-standard Fetch API for Node.js. It provides a promise-based interface for making asynchronous network requests to retrieve or send data from server-side environments. The project specializes in memory-efficient data handling by utilizing request and response streaming. This allows for the incremental processing of large network payloads through native system streams to prevent memory exhaustion. The library covers a broad range of networking capabilities, including the use of custom HTTP agents for DNS and SSL config

This project is a Node.js HTTP reverse proxy middleware designed to route incoming HTTP and WebSocket traffic to target backend services. It functions as a dynamic routing engine and API gateway tool, providing the capability to consolidate multiple backend services behind a single entry point. The middleware features a WebSocket proxy bridge that manages protocol upgrade handshakes to maintain persistent bidirectional communication. It also includes a request and response transformer used to intercept and modify headers, bodies, and URL paths during transit. The system provides broad traffi

Rack Middleware for handling Cross-Origin Resource Sharing (CORS), which makes cross-origin AJAX possible.

This module provides a convenient alternative to XMLHttpRequest. For example, to load a text file:

All over again. Includes support for xmlHttpRequest, JSONP, CORS, and CommonJS Promises A.

A Go HTTP client library for creating and sending API requests

Easy Mock is a tool for API mocking and simulation that allows for the creation of fake server responses using schemas. It enables the generation of mock API data and the implementation of OpenAPI specifications to align development with technical contracts. The project supports collaborative API design through a shared workspace where team members can synchronize and manage mock endpoints. It also features specification-driven bootstrapping, which automatically constructs mock environments by importing standard API definition files. The system provides API development proxying to forward re

http-prompt is an interactive HTTP client and API testing CLI designed for constructing and debugging network requests to REST and GraphQL endpoints. It functions as a command-line request builder and a shell extension built on top of HTTPie. The tool provides an interactive shell interface featuring request autocomplete and real-time syntax highlighting for requests and responses. It incorporates stateful session management to maintain request history and session data across multiple commands. The project covers API request automation and REST API debugging, allowing users to send and verif

This project is a comprehensive Python network request framework designed for both synchronous and asynchronous HTTP communication. It provides a high-performance client capable of executing non-blocking requests within event-driven applications, while also supporting standard blocking calls for simpler scripts. The library is built to operate natively across diverse asynchronous runtimes, automatically detecting and utilizing the underlying event loop for concurrency. What distinguishes this library is its modular architecture, which decouples request construction from network execution thro

Usable, fast, simple HTTP 1.1 for Ruby

Node.js framework agnostic library that enables you to forward an http request to another HTTP server. Supported protocols: HTTP, HTTPS, HTTP2

Global HTTP/HTTPS proxy configurable using environment variables.

This project is a JavaScript fetch polyfill and HTTP client library. It implements the Fetch API in environments that lack native browser support for web requests, providing a promise-based network wrapper for executing asynchronous HTTP calls and managing responses. The library ensures a consistent interface across different JavaScript runtimes by mapping raw network data into standardized request and response objects. It utilizes the XMLHttpRequest object to perform network operations in environments where a native fetch implementation is unavailable. The tool covers HTTP request managemen

Resty is a high-level HTTP client library for Go designed for consuming REST services. It provides a streamlined interface for executing network requests, managing server-sent event streams, and automatically mapping JSON and XML responses into data structures. The library includes built-in mechanisms for service resilience and traffic management, such as circuit breakers to prevent cascading failures, token-bucket rate limiting, and automated request retries with exponential backoff. It also features client-side load balancing to distribute outgoing traffic across multiple base URLs and requ
