Hoppscotch: open-source alternative to Postman

About Hoppscotch

Hoppscotch is an open-source API development ecosystem for sending requests, inspecting responses and organizing API work. It is positioned as an alternative to Postman and Insomnia and runs in the browser, as a desktop app and from a command line interface, with offline, on-premises and cloud options.

The request builder supports the standard HTTP methods plus custom ones, and the toolset extends to GraphQL and WebSocket testing. You can generate code snippets for more than ten languages and frameworks, share requests through public URLs, and install the web app as a progressive web app for offline use. The interface is lightweight, with light, dark and black themes, a choice of accent colors and a distraction-free Zen mode.

Hoppscotch is MIT licensed and written mainly in TypeScript with Vue. Teams that need to keep API traffic and collections inside their own network can self-host it, while the hosted service at hoppscotch.io suits individuals who just want to start sending requests.
