Hey Product Hunt community! 👋 I built NetCheck because I was frustrated with basic speed tests that don't tell the whole story. As a developer, I needed comprehensive network diagnostics that could help troubleshoot connectivity issues, not just measure download speeds. What makes NetCheck unique: 🔍 Complete network analysis - IP info, NAT type, BGP routing, latency, and speed testing in one place 🌍 Multi-language support (English/Chinese) for global accessibility ⚡ Real-time results with detailed technical insights 🛠️ Built specifically for developers, IT professionals, and network enthusiasts I'm most proud that NetCheck provides professional-grade network diagnostics that are accessible to everyone. Try it out and let me know what you think! What network issues have you been struggling with?
