Seems like it might be handy for testing. Certainly good to stay way from it for production apps though.
I built http://jsonblob.com for this purpose. It has an HTTP API as well as we nice GUI interface to edit your JSON. It's open sourced and really just a thin webapp on top of mongo, so it's easy to run your own.
A JSON literal is also valid JSON. Therefore 4, "test" and true should be saveable without a object wrapper
Could be used for notepad API or something public. That said, it seems that services like Parse and Firebox seem more robust and also have faster response times.
I can't see the use case of this. If it was editable after saving then that would make sense, but this is just static. And being static, you're better off just bundling it with the app. Unless I'm missing something?
Nice presentation though, the site looks nice.
EDIT: I see you can create and update through the HTTP API, which makes it much more useful.
Neat, but it would be neater if this were open source and running on https.
Why not use https://www.firebase.com? Seems more reliable (Privacy Policy, ToS, SLA) and easier to start using, and it has a free tier if you need something quick for development.
I built a similar thing, in Go on App Engine: https://github.com/imjasonh/simply-put
for anyone interested in a an easy tool for building JSON store/APIs, you might find HiveMind (crudzilla.com) useful, I am the developer.
Here's a simple screencast: http://crudzilla.com/assets/img/info-graphics/instantiator.g...
There's a lot that you can with it, in terms of generating JSON.
For testing purposes, wouldn't using Dropbox suffice as well? It gives a quick way to update the JSON and see changes occur near live in app?
Could you do this for an excel document (database)?
It would be cool to be able to drag and drop an excel document into here and call it with a url.
Seems simple and useful like jsfiddle. I will really use this in my app.
Maximum nesting depth of 100 :( or else it says it's invalid JSON.
Neat and simple, but that's exactly the kind of things that makes me go "too bad it's not open sourced, I could use that"
