I looked into using Bruno ever since Postman enshittened the free client. I ended up just installing the version of Postman pre collections being removed and ignoring the prompt to update.

I'm struggling to remember the reason I didn't stick with Bruno. I think it was due to not having an equivalent to Postman's pre-request scripts. If that could be added, I'd certainly give Bruno another try.

Edit: Another comment has mentioned that Bruno now has (or maybe always had and I just didn't see) pre request scripts.
