Hoppscotch

Hoppscotch is a lightweight, open-source API development suite that serves as the leading alternative to Postman. In the 2026 market landscape, Hoppscotch distinguishes itself through its browser-native architecture and commitment to decentralization and privacy. Built with Vue.js, it operates directly in the browser with minimal overhead, leveraging browser extensions to bypass CORS limitations without requiring a dedicated desktop client. It supports a comprehensive range of protocols including REST, GraphQL, WebSockets, Server-Sent Events (SSE), Socket.io, MQTT, and gRPC. Its technical architecture facilitates real-time collaboration through its 'Teams' cloud offering while maintaining a 'self-host first' philosophy for enterprise compliance. As organizations move toward sovereign developer environments, Hoppscotch's ability to be deployed on-premise or in private clouds via Docker makes it a critical tool for industries with high security requirements. The 2026 version features enhanced AI-driven test generation and automated documentation synthesis, positioning it as a core component of the modern API-first development lifecycle.
