Jetbrains has a pretty cool HTTP/REST client: https://www.jetbrains.com/help/idea/http-client-cli.html

The 'UI' (which is really an editor/syntax highlighting for the .http files) version I believe is a paid feature on the IDEs, but the CLI one I believe you don't need to pay to use it.

This is a good option. Wish there was a GUI but this works as well
