Great question! For VS Code, I recommend the REST Client extension — it lets you send HTTP requests directly from .http files, making testing APIs super easy without leaving the editor. It’s lightweight and very popular among devs.

There are also some others like Thunder Client if you want a more Postman-like experience inside VS Code.

Thunder Client is a good client.
As Emmanuel said, it's similar to Postman, but with fewer features.

Ouch! You did a whole 20 and missed voiden.md

For the most it's well known where they differ, some are a tad less popular so I'll look more into them :)

My heart is shattered, I just found out my husband has been cheating on me with his best friend. Something in my gut told me things weren’t right, so I decided to check his devices. Thanks to a talented hacker ( Zattechhacker A T gma il co m ) , recommended by my colleague, I now have the proof I needed. I’m overwhelmed with emotions, hurt, betrayal, but also relief that I finally know the truth

Interesting: didn't know these existed. Actually I really like the integrated /docs endpoint inside FastAPI because it's highly coupled with the code.

Missed Posting.sh too, slick UI, capable of full keyboard control, and the API collections are all yaml so easy for git control.
