Hoppscotch • Open source API development ecosystem
Helps you create requests faster, saving precious time on development.
Categories:
Hoppscotch is an open-source API development ecosystem and lightweight, fast alternative to Postman and Insomnia for building, testing, and collaborating on APIs.
🚀 Overview
Hoppscotch provides a minimalistic yet powerful interface for crafting API requests in real-time, supporting protocols like HTTP, GraphQL, WebSocket, Server-Sent Events, MQTT, and Socket.IO. It eliminates the need for bloated tools by offering offline PWA support, desktop apps, and CLI options.
This project solves common pain points in API development such as vendor lock-in, high subscription costs, and lack of flexibility in proprietary clients like Postman. It enables quick request testing, collection management, and team collaboration without compromises.
Built for developers, QA engineers, and teams iterating on APIs during development. The community-driven project was created to offer a free, extensible, self-hostable ecosystem that prioritizes speed, privacy, and openness.
✨ Key Features
- Real-time request/response handling with syntax-highlighted previews for JSON, XML, HTML, images, etc.
