What our customers are saying

The best tool for JSON.

Well thought through with lots of nice features for inspecting JSON, such as paste, search, and the highlighting makes it easy to inspect JSON (looks nice too). The app serves my needs very well -- simple to use yet effective. Thanks!

My go to JSON viewer

hotshew

I use OK JSON every day. It’s super handy, has great integration with RayCast, and makes it very easy to filter down JSON

Can’t work without it

MOOSELOCK

OK JSON quickly and beautifuly displays JSON payloads. Very easy to navigate and find keys and values. Very helpful for debugging APIs.

Great app for API work

I use it every day. The author is also super responsive and open to suggestions. Simply a great tool. Highly recommend it.

Great JSON reader

GermanInMontreal

I wanted a simple JSON reader that is local to my machine and will not push any sensitive content to the cloud. It read a chunky 6MB JSON file with no issues.

Exactly what the Dr. Ordered

SayYesToAwesome

JSON makes my head hurt and this app has already been extremely helpful to make sense of it. It's simple to use and has an esthetically pleasing UI. Having it on my own machine is super nice as well. Thanks for this!

Super useful
