Hoppscotch is an open-source API development tool, positioned as an alternative to Postman and Insomnia. It supports REST, GraphQL, WebSocket, Server-Sent Events, Socket.IO and MQTT, and offers collections, environments, pre- and post-request scripts, code snippets and several authorisation methods including OAuth 2.0 and OIDC. Teams can share workspaces with role-based access control. Hoppscotch is available as a web app, a desktop app and a command-line tool, either as a hosted service at hoppscotch.io, where data syncs across devices after sign-in, or self-hosted.
The Hoppscotch company is based in India; third-party profiles place its headquarters in Kochi, Kerala. The code is published under the MIT licence. The free Community Edition can be self-hosted on your own infrastructure, including within the EU, which keeps collections and credentials in your environment. The Enterprise Edition adds SAML-based SSO, OpenID Connect and audit logs. When using the hosted service, request data is synced to the vendor's cloud, and the official proxy is also hosted by Hoppscotch, so organisations with strict data requirements should prefer self-hosting.
