What is hoppscotch/hoppscotch?
Hoppscotch is an open-source API client and testing platform that lets developers make HTTP requests, test REST APIs, and work with GraphQL endpoints across web, desktop, and CLI environments. It's a free alternative to tools like Postman that works offline or can be self-hosted, making it useful for developers who want to avoid vendor lock-in or need on-premises deployment. The platform supports API testing, request building, and collaboration features, with availability as both a progressive web app and native desktop applications.
