mDNS Discovery is a lightweight Windows utility for Multicast DNS (mDNS) and DNS Service Discovery (DNS-SD) on your home or office network. Use it to discover Bonjour- and Zeroconf-style services nearby, inspect connection details, and broadcast (advertise) your own service when you need a quick test endpoint.\n\nDiscover (browse)\nAdd one or more DNS-SD types (for example _http._tcp, _https._tcp, _ssh._tcp) and watch services appear in real time. Filter by name, type, host, port, or TXT fields. When a host is still unresolved, resolve host & TXT to finish the picture. Copy individual fields or the full JSON payload for debugging, documentation, or automation notes.\n\nBroadcast (publish)\nCreate a local advertisement with service name, type (TCP/UDP), port, and TXT attributes\u2014handy for prototyping, demos, or verifying that other devices can see your machine on the LAN.\n\nBuilt for clarity\nClean tabs for Discover vs Broadcast, readable service cards, and quick copy actions so you spend less time retyping addresses and more time shipping.\n\nNote: Publishing requires a free port and OS / firewall permissions for local networking. Discovery depends on your network allowing multicast traffic typical of mDNS / Bonjour / Zeroconf environments.
