Who hunted JSON Ox?
JSON Ox was hunted by Tom. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it.

Thanks for checking this out 👋
We built this as a free, private, in-browser JSON formatter. The goal was to keep it lightweight and reliable for everyday debugging—without sending any data to servers or adding unnecessary complexity.
It’s intentionally simple, but a few things under the hood matter to us:
Everything runs locally in your browser
Works as a PWA (installable, offline-capable)
No tracking or server-side processing
Fast performance, even with large JSON files
We’ve also focused heavily on security and performance from day one:
Strong security headers - Mozilla Observatory
Fast load and runtime performance - PageSpeed Insights
We’d love your feedback on:
What’s missing from your workflow today
Whether the UX feels clear and fast
Any edge cases that break things
Appreciate any thoughts, suggestions, or critiques 🙏
