HTTPie is a modern API testing platform designed to make interactions with web services and APIs as human-friendly as possible. The platform consists of two main components: HTTPie for Terminal (the original open-source command-line tool) and HTTPie for Web & Desktop (a commercial GUI application currently in public beta). The open-source HTTPie Terminal is completely free and widely adopted by developers worldwide, with 47,961 GitHub stars. It's designed for simplicity and readability, featuring automatic JSON formatting, outstanding color syntax highlighting, and easy handling of authentication. Developers at major technology companies rely on HTTPie Terminal for API testing and debugging, particularly when working with JSON-based APIs and troubleshooting backend issues. HTTPie AI, integrated into the Web & Desktop versions, transforms API testing through advanced natural language processing. Users can describe requests in detail or provide high-level task specifications for common APIs, and the AI generates the appropriate HTTP requests automatically. The GUI versions offer additional features including HTTP methods in tabs, library context menu, cURL input mode, and the ability to organize work in spaces, collections, and tabs with parameters, variables, and environments. HTTPie Web & Desktop support real-time synchronization across devices with auto-save, allowing teams to collaborate seamlessly. The platform enables users to start testing REST, GraphQL, and HTTP APIs from the browser in seconds, with no account required for basic usage. While the terminal version is free and open source (BSD-3-Clause license), the commercial GUI version requires contacting the vendor for custom pricing quotes.
