I'm currently exploring clients options for testing REST APIs and GraphQL endpoints and I'm eager to learn about the clients and tools you have used for this purpose. In particular, I'm interested in understanding whether you've come across proprietary or open-source solutions that can be self-hosted.
On a related note, I've personally used tools like Postman, ThunderClient, and RapidAPI as VS Code extensions for API testing. If you have any recommendations or insights regarding self-hosted REST API / GraphQL testing clients, please share your experiences and suggestions. Thank you!
