👋 Hi Product Hunt! I'm the solo indie dev behind BestOfTool.
As a developer, I constantly found myself needing to quickly format messy JSON payloads, validate syntax errors, or convert JSON into CSVs for reporting.
But I had a massive problem: Privacy. Almost all the top Google results for "JSON Formatter" upload your pasted text to their backend servers. When you are dealing with proprietary API responses, live webhook data, or real customer payloads, pasting them into random online tools is a massive security risk.
So, I built BestOfTool to solve this. It features 15+ data utilities that process your data 100% locally in your browser using WebAssembly and JS.
✅ Zero server uploads. ✅ Instant parsing speeds (no network lag). ✅ Handles massive files easily. ✅ Completely private.
I built this over the last few months and I'm incredibly excited to share it with you all today. I'm actively hanging out in the comments all day—please let me know what you think, or if there is a specific tool you'd like to see added next! 🚀
