Ask HN: Collaborative json data model design tools?

Title kind of explains it all. I'm looking for essentially a Google Drive for json data modeling that I can use with a team to iterate on API request/responses formats. Would need syntax highlighting, versioning history, maybe comments too?

I think I could use a gist for this, or a whole repo with each one in there as a single .json file, but curious if there are tools out there specifically for this.

Thanks!
