You can use Hoppscotch to create, send, and inspect HTTP requests directly from your browser. It serves as a lightweight alternative to desktop API clients, allowing you to configure request parameters, headers, authentication methods, and body payloads with ease. You can organize your endpoints into reusable collections, manage dynamic environment variables, and run pre-request or post-request scripts to validate responses. It also supports real-time protocols like WebSocket, Server-Sent Events, and MQTT, making it easy to test backend services and debug network issues quickly without installing heavy local software.
