# 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. Source: https://altcatalog.com/alternatives/hoppscotch/ Category: API clients ## Overview - **Who it's for**: 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. - **What you get**: 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. - **How it works**: 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. ## Profile - **License**: MIT (verified 2026-07-08) - **Pricing model**: OSS + paid hosting (verified 2026-07-08) - **Starts at**: Free (verified 2026-07-08) - **Platforms**: Web, Windows, macOS, Linux - **Status**: active (verified 2026-07-08) ## Ranked alternatives | # | App | Alt Score | Licence | Platforms | |---|-----|-----------|---------|-----------| | 1 | [Bruno](https://altcatalog.com/alternatives/bruno.md) | 100 | MIT | Windows, macOS, Linux | | 2 | [Insomnia](https://altcatalog.com/alternatives/insomnia.md) | 100 | Apache-2.0 | Windows, macOS, Linux | | 3 | [Yaak](https://altcatalog.com/alternatives/yaak.md) | 96 | MIT | Windows, macOS, Linux | | 4 | [Postman](https://altcatalog.com/alternatives/postman.md) | 78 | Proprietary | Windows, macOS, Linux, Web | | 5 | [HTTPie](https://altcatalog.com/alternatives/httpie.md) | 55 | BSD-3-Clause | Windows, macOS, Linux, Web | Alt Score = Verified coverage (90%) + Visibility (10%).
