Postman feels bloated—any lightweight alternatives for API testing?

Hi folks,

I use Postman regularly for API testing, but it’s getting slow with larger collections and the UI can be sluggish. I’m looking for something more streamlined that still supports:

  • Importing OpenAPI/Swagger specs

  • Quick GET/POST testing

  • Markdown or CI-friendly setup

Bonus if it’s CLI/GUI hybrid and easy to integrate with Git and CD workflows.

Has anyone switched to a better alternative? Appreciate your insights
