Profile

Hi everyone,I built NatChecker – a free online tool that helps users easily check their network’s NAT type with one click, no login or setup required.Many gamers and developers who use peer-to-peer (P2P) networking need to know their NAT type — for example, when hosting multiplayer games or running PCDN (peer-to-peer content delivery). A good NAT type (like Full Cone / NAT1 / NAT2) makes it easier to connect or host, while stricter types (Symmetric / NAT3) can block connections.The tool runs entirely in your browser using WebRTC and public STUN servers, without collecting any data or requiring an account. My goal was to make NAT detection simple, private, and instant.Feedback and suggestions

NatChecker – free online NAT type detector (no login, one click) is positioned in show hn launch, a segment that rewards a clear, focused offering.

The company is listed at the Show HN launch stage of development.
