Hoppscotch

Hoppscotch is a lightweight open-source tool for API development, debugging, testing and sharing. It supports multiple protocols — including HTTP, GraphQL and WebSocket — and offers cross-platform clients for web, desktop and CLI environments.

While the API tooling space is crowded with alternatives like Postman, Insomnia and Bruno, Hoppscotch stands out for its lightweight footprint and privacy-friendly design. It omits analytics, uses local-first storage and supports self-hosting. It’s a strong choice for organizations seeking an intuitive way to share API scripts while maintaining strong data privacy.
