I built a free JSON Viewer that never uploads your data — here's how

As a developer, I constantly paste JSON into online tools — but always felt uncomfortable about where that data was going. So I built JSON Viewer Pro.

What it does
Paste JSON → instant collapsible tree view
Click any node → get the JSONPath ($.user.address.city)
Search across all keys and values
Format or minify with one click
Dark & light theme
The privacy angle
The entire app is a single HTML file served from Cloudflare. There is no backend, no database, no analytics. Your JSON is processed entirely in your browser using JSON.parse().

Try it
https://jsonviewer.live

Built with vanilla JS, no frameworks. Happy to answer questions in the comments!

Firefox has had a decent built-in JSON viewer for as long as I can remember
