Hoppscotch

Meet Hoppscotch

Hoppscotch is an open-source API client for building requests, inspecting responses, and sharing API work with a team. You can send HTTP requests, explore GraphQL endpoints, or connect to services that use protocols such as WebSocket. Save requests in collections, then use environment variables to switch between development and production settings.

Pre-request scripts can prepare authentication or modify headers, while response tests check the data an endpoint returns. Shared workspaces include access roles and request history. Hoppscotch also provides desktop and web clients, code snippet generation, and a command-line interface for running saved requests in automated workflows.
