JSON is text but not all text files are equal for git versioning. A lot of tools like Postman save(d) their data in a big JSON file, often minimified, making it absolutely impossible to natively use git diffing and merging. Which makes collaboration impossible. Collaboration is then sold as an add-on, and for Postman only through Cloud sync.

Postman added a new file format this year. It now does what Bruno was doing since the beginning : one file per request for easy diffing and merging.

Bruno definitely had an edge. And it lost it because LLMs left no choice to Postman but to adopt something similar.
