Hey Product Hunt! 👋 I'm excited to launch JSONHub today - a free, privacy-focused JSON formatter that developers actually want to use. The Problem: As a developer, I was frustrated with existing JSON tools. They're either cluttered with ads, require sign-ups, or don't respect your privacy by sending data to servers. Plus, most lack the small features that make a huge difference - like auto-formatting on paste or keyboard shortcuts. What Makes JSONHub Different: ✨ Auto-format on paste - Instantly beautifies JSON the moment you paste it 🔒 100% client-side - Your data never leaves your browser ⌨️ Keyboard shortcuts - Built for power users (Cmd/Ctrl+K to format) 🤖 AI-optimized formats - Convert JSON to TOON format for better LLM context 🎨 Dark mode - Easy on the eyes during late-night debugging 🚀 Works offline - No internet required after first load Built for developers who care about: Privacy (no tracking, no data collection) Speed (instant formatting, no server round-trips) Simplicity (clean UI, no feature bloat) I'd love to hear your feedback! What JSON tools do you currently use, and what features would make your workflow easier? Try it out and let me know what you think! 🚀
