Alternatives to Hoppscotch
Open source web-based API client
Hoppscotch ranks #4 of 6 in API clients, with an Alt Score of 85. It is licensed under MIT, open source with paid hosting from Free and available on Web, Windows, macOS and Linux. 11 of 12 checklist rows are verified against a public source.
Developers and QA/API teams who build, test, and debug REST, GraphQL, WebSocket, and other real-time APIs, especially those wanting a faster, lighter, self-hostable alternative to Postman.
A browser-based (and desktop/PWA) client for sending requests and inspecting responses across REST, GraphQL, WebSocket, SSE, Socket.IO, and MQTT. It includes collections, environments, variables, pre-request/test scripts, and team workspaces with role-based sharing. It's fully open source and can be self-hosted or used via the hosted app, with a CLI for running collections in CI.
You build requests in a UI organized into collections and environments, send them directly from the browser (using a companion browser extension or proxy to bypass CORS when needed), and view live responses; scripts can run before/after requests for setup and assertions, and everything can sync to a team workspace or run headlessly via the CLI.
