Hey hunters! 👋 Harshit here, the maker of JSON Viewer Pro. I built this because I was tired of pasting sensitive API responses and config data into tools that send everything to a server. JSON Viewer Pro runs 100% in your browser — the code is a single HTML file on Cloudflare's CDN, there is literally no backend to send data to. A few things I'm especially proud of: The tree explorer — click any node and it collapses/expands instantly. Handles deeply nested JSON with thousands of keys without slowing down. JSONPath on click — click any value and the path bar at the bottom shows the exact JSONPath ($.users[0].address.city). Copy it in one click. Saves so much time when writing queries. It's fast — no React, no Vue, no build step. Pure vanilla JS. Loads in under 100ms on a slow connection. I use it daily at work for debugging API responses. Would love to know what features you'd want next — better search? Export to CSV? YAML support? Try it at jsonviewer.live and let me know what you think!
