Hey Product Hunt! 👋 I built DevJSON because I was tired of having a graveyard of bookmarked "JSON formatter" websites, half of which were slow, ad-stuffed, or quietly questionable about what happens to the data you paste in. As a developer, I wanted something that: Opens instantly in a new tab Handles JSON and XML (XML tooling online is surprisingly bad) Lets me actually explore the data — not just pretty-print it — with a real tree view and copyable paths Never sends anything anywhere, because pasting production API responses into a random website is a bad habit I wanted to break DevJSON is the result. It's intentionally simple: no accounts, no cloud sync, no "upgrade to Pro to copy more than 3 paths" nonsense. Just a clean, fast, keyboard-friendly tool that does one job well. This is an early release and I'm actively shipping improvements — diffing, more formats, and export options are on the roadmap. I'd love your feedback on what would make this part of your daily workflow. Thanks for checking it out! 🙏
