Nib

What is Nib?

Nib is a tiny, fully native macOS API client, and a free alternative to Postman, Insomnia, Bruno and Hoppscotch. About 3.2 MB on disk and roughly 30 MB of memory. Drop in a Postman export and your whole workspace comes across. Your requests stay as plain JSON files in a folder you pick, so you can diff them and commit them alongside the code they talk to.
