ZeroScan finds devices on your network that advertise Bonjour (mDNS / DNS-SD / zeroconf) services. It shows each one’s name, IP address, the services it offers and the ports they’re on, without probing your network. See what’s on your network Watches for 85 service types, including SSH, HTTP, AirPlay, printers, HomeKit and file sharing. You can add any other service type in preferences. Icons show what kind of device each one is likely to be: computer, phone, TV, printer, camera, router, storage and more. Shows each service’s TXT record, so you can see model names, firmware versions and device IDs. Results refresh on their own. You choose the rescan interval and how long a device stays listed after it stops advertising. Spot what changed Save a snapshot of a network and name it, like “Home” or “Office.” ZeroScan suggests which saved network you’re probably on. Compare the live scan with any saved snapshot. Devices are marked new, changed or gone, along with the services and ports that were added, removed or moved. “Show Changes Only” hides everything that hasn’t changed. Rename, merge or delete saved networks and snapshots. Take results with you Export the full scan as CSV or JSON. Copy a hostname, IP address or port list in the format you pick. On iOS, open HTTP, HTTPS, SSH and SFTP services directly in the app that handles them. What ZeroScan isn’t ZeroScan isn’t an IP scanner. It listens for devices that announce themselves and never probes addresses. A device that doesn’t advertise one of the services ZeroScan watches for won’t appear. Privacy ZeroScan collects no data and sends nothing off your device. Your snapshots and preferences are saved on the device and nowhere else.
