Hoppscotch

Hoppscotch is a fast, lightweight, open-source API development tool used for testing and interacting with APIs directly from the browser. It allows developers to send HTTP requests such as GET, POST, PUT, and DELETE, inspect server responses, and debug backend services efficiently. The platform supports multiple protocols including REST, GraphQL, WebSockets, and MQTT, and provides features like authentication handling, environment variables, request collections, and collaboration tools. Built with modern web technologies like Vue.js and Node.js, Hoppscotch serves as a fast and open-source alternative to Postman, making it widely used by developers for API development, testing, and debugging.
