About Hoppscotch

Hoppscotch is a free, open-source API development ecosystem that helps developers build, test, document, and collaborate on APIs through a lightweight, fast web-based interface. It supports REST, GraphQL, WebSocket, MQTT, SSE, and Socket.IO protocols, making it one of the most versatile API testing tools available. With over 2.5 million users and processing more than 5 million API requests monthly, Hoppscotch has become the fastest-growing open-source API development platform and a compelling alternative to Postman for developers who prioritize speed, simplicity, and open-source principles.

Hoppscotch differentiates itself with a blazing-fast, browser-first experience that requires no installation for its web version, while also offering desktop applications and a CLI for automated testing workflows. The platform includes environment and variable management, request collections with folder organization, pre-request scripts, test assertions, real-time collaboration through shared workspaces, and a self-hosting option for teams that need to run Hoppscotch on their own infrastructure. Its minimalist design loads instantly and provides a distraction-free interface focused purely on API interaction.

Hoppscotch targets individual developers, QA engineers, and small teams who need a quick, no-friction API testing tool without the overhead of account creation, cloud sync, or subscription fees. It is particularly popular among frontend developers testing backend endpoints, students learning API development, and open-source contributors who value transparency and community-driven development. Hoppscotch integrates with CI/CD pipelines through its CLI tool and supports importing collections from Postman, Insomnia, and OpenAPI specifications, making migration from other tools straightforward.
