Hoppscotch

Hoppscotch is an open source API development ecosystem for sending, testing and organising API requests. It is available as a web application, a desktop application and a command-line interface, and can be used offline, deployed on-premises or used through the hosted cloud service.

Requests are organised in collections, with environment variables and a request history. Teams share workspaces with access control and real-time collaboration, and organisations can self-host the platform.

Hoppscotch is distributed under the MIT licence and is actively developed on GitHub.
