Hoppscotch

Hoppscotch is an open-source API development platform that provides developers with a fast, lightweight environment for testing and debugging APIs. It supports multiple protocols including REST, GraphQL, WebSocket, SSE, Socket.IO, and MQTT, making it a versatile tool for modern API development workflows. The platform runs entirely in the browser with no installation required, offering both a cloud-hosted version and self-hosted options.

• REST API Testing allows developers to send HTTP requests with full support for query parameters, headers, request bodies, and authorization methods including OAuth, Bearer tokens, and API keys.

• Pre-request and Post-request Scripts enable JavaScript-based automation before sending requests and after receiving responses, supporting environment variable manipulation and response assertions.

• Collections Management organizes API requests into reusable collections that can be imported, exported, and shared across teams for collaborative development.

• Environment Variables support multiple environments (development, staging, production) with variable substitution in URLs, headers, and request bodies.

• History Tracking automatically saves all sent requests for easy reference and re-execution without manual documentation.

• Code Snippet Generation converts API requests into code snippets for various programming languages and HTTP clients.

• Mock Servers allow developers to create simulated API endpoints for testing without backend dependencies.

• Shared Requests enable team collaboration by sharing individual requests or entire collections with workspace members.

To get started, visit hoppscotch.io and begin testing APIs immediately in your browser. Create collections to organize your requests, set up environments for different deployment stages, and use pre-request scripts to automate repetitive tasks. The platform integrates seamlessly into development workflows with support for importing collections from other API tools.
