Two Free, Open-Source API Debugging Tools: Hoppscotch and HTTPie

Hoppscotch is a browser-based API debugging and testing tool with near-full Postman feature parity. Key capabilities include request creation, persistence, real-time API docs generation, team collaboration, proxy configuration, WebSocket/SSE support, GraphQL querying, and MQTT cleint connectivity. It eliminates Postman’s common pain points such as slow foreign server synchronization, mandatory local installation, and separate account requirements—GitHub login is natively supported for quick access and data sync. The UI is minimalist and intuitive, optimizing workflow efficiency.

HTTPie provides both a clean browser interface (HTTPie for Web) and a cross-platform CLI client designed to streamline CLI-to-API inetractions. The CLI prioritizes readability and simplicity over traditional curl syntax, featuring expressive formattnig, syntax highlighting, native JSON support, file/table uploads, session persistence, proxy/SSL/auth integration, and Wget-like download functionality. It is available on Linux, macOS, Windows, and FreeBSD, with installation options including Python’s pip package manager.
