> [for every] Jetbrains IDE there's a builtin rest client that works well

There's also one available as a major mode for Emacs: https://melpa.org/#/restclient

If the command line is acceptable but you want more of a focus on usability than curl has, there's httpie (https://httpie.io/) and its clone xh (https://github.com/ducaale/xh).

The JetBrains IDE, Visual Studio, and VS Code all support http files as well, which can be checked into an application.
