I've landed on the REST extension in VS Code for development and interactive work, and Hurl for more test/automation stuff. Both take a little more effort to get setup but way more productive than the typical Postman workflows I see.

Idk if they have it yet, but last time I used the VS Code REST extension it still didn't support pre/post request scripting (which is already insanely fragmented syntactically across Postman/Insomnia/Bruno).

For any long-term things that would normally be in a Postman collection and distributed to others / outside teams, I usually end up with folder-separated Hurl scripts (similar to your use).

I can totally see how the REST extension is way easier for point & shoot from within VSCode though!
