Hi Product Hunt! 👋 I'm zhisan, solo developer behind ByteJSON. Why I built this: After years as a developer, I was frustrated by online tool sites: 1. **Privacy concerns** - Most tools send your JSON/configs to servers. Not ideal when debugging API keys or sensitive data. 2. **Registration walls** - Why do I need an account just to format some JSON? 3. **Ad overload** - Popups everywhere, tools barely usable. So I built ByteJSON differently: - Everything runs in YOUR browser (client-side JavaScript) - Zero registration required - Clean interface, minimal ads - Works offline once loaded - Tools + tutorials included Tools I personally use daily: - JSON Formatter (for API debugging) - UUID v7 Generator (new time-ordered standard) - Regex Explainer (finally understand complex patterns!) What's next: - More developer tools (your requests welcome!) - API integration tutorials - Performance optimizations What tool would you add? Feedback much appreciated! 🙏 --- P.S. If you find this useful, an upvote helps other developers discover it. Thanks!
