Hoppscotch

Hoppscotch is an open‑source ecosystem for creating, testing, documenting and sharing API requests. It provides an API client where users can configure URLs, parameters, headers, bodies, and authentication, then view responses directly. The platform also supports pre‑request scripts and post‑request tests, allowing developers to automate request modification and response validation.

The tool is designed for individual developers and teams, offering workspaces, role‑based access, real‑time collaboration, and audit logs. Collections and folders let users organize requests, while environment variables enable reuse across projects. Deployment options include a cloud service and an on‑premises version that can be self‑hosted from the GitHub repository. Integration with single‑sign‑on and an admin dashboard facilitates user and workspace management.

Hoppscotch runs on macOS, Windows, Linux, web browsers and a CLI, and it is available in more than thirty languages. It processes millions of requests each month and is positioned as a comprehensive, cross‑platform solution for the full API development workflow.
