Hoppscotch Overview
Hoppscotch is a free, open-source API development and testing tool for Windows, macOS, and Linux (and the web), a lightweight alternative to heavier API clients. It lets you build and send HTTP requests, work with REST, GraphQL, and real-time protocols like WebSocket and Server-Sent Events, organize requests into collections, manage environment variables, and write tests, all in a fast, minimal interface. Being open source and largely browser-based, it is easy to self-host and use without a heavy install. It appeals to developers who want a quick, no-frills tool for exercising and debugging APIs. The full offline installer bundles the application and installs without an internet connection, though calling remote APIs needs connectivity. It also supports request history, code generation for many languages, and a browser extension to bypass CORS during testing. This page links to the official Hoppscotch download.
