Best Lightweight Tools for API Testing During Workflow Development?

I’m building some complex workflows that involve a lot of API calls between different services.

I’ve been using my usual API client ( Postman ) , but it’s starting to feel too heavy, especially when I just want to quickly validate a few requests or debug something inside a Latenode flow.

I’ve seen mentions of Bruno and a few others , does anyone have a favorite lightweight API client that’s fast but still powerful enough for things like:

  • Auth testing (OAuth, API Keys)
  • Chaining requests
  • Quick documentation generation?

Would love to hear what’s working well for faster iteration during your Latenode builds.
