Hoppscotch is a free, open-source API development platform with 78,000 GitHub stars and it’s replacing Postman for thousands of developers worldwide. In this short, we break down exactly what it does and why teams are ditching their paid subscriptions for it. Hoppscotch supports REST, GraphQL, WebSocket, MQTT, and Server-Sent Events all in one clean interface. You get environment variables, request collections, pre-request scripts, post-request tests, and full team collaboration — no installation needed, runs straight in your browser. It also ships as a desktop app for Windows, Mac, and Linux, works offline, and can be fully self-hosted on your own server with Docker. Postman charges up to $49 per user per month for these features. Hoppscotch is completely free. #hoppscotch #postmanalternative #opensource #developertools #webdevelopment
