RecipeUI is rethinking how we use API tools like Postman or Insomnia. We're starting off with TypeScript powered API requests and API collections you can run in seconds!

Insomnium is described as 'Fast local API testing tool that is privacy-focused and 100% local. For testing GraphQL, REST, WebSockets and gRPC. This is a fork of Kong/insomnia' and is a API Client in the development category. There are more than 25 alternatives to Insomnium for a variety of platforms, including Linux, Mac, Windows, Flathub and Flatpak apps. The best Insomnium alternative is Bruno, which is both free and Open Source. Other great apps like Insomnium are Postman, Insomnia REST Client, Yaak and Hoppscotch.
