Spiceworks IP Scanner
Discover the devices on your network automatically with the Spiceworks IP Scanner for basic information like OS and MAC Address. Or get detailed hardware and software information on your workstations and servers like CPU, storage, memory, installed software, serial number, and lots more. Get the information you need, with minimal setup! IP Scanner is a cloud tool that scans your local network and returns a sortable list of the devices it discovers. Devices can be filtered, searched, and exported to CSV. By default, it detects and scans a local subnet, though you can also define a custom IP range. The IP Scanner lists each device’s hostname, IP address, vendor, OS, MAC address, description, open ports, and if it’s up or down. The kind of data returned depends on the type of device being scanned.

Subnetlens
Subnetlens is a local-first Windows desktop app for network discovery, LAN monitoring, and IT troubleshooting. It scans and classifies devices, builds an interactive topology map, tracks per-device port and service history, listens for mDNS/SSDP device activity in real time, and includes 26 built-in diagnostic tools such as ping, traceroute, DNS lookup, port scan, WHOIS, GeoIP, TLS checks, HTTP header inspection, and more. Pro features include Radar monitoring, Prometheus metrics, scheduled scans, risk scoring, HTML reports, IPAM, webhooks, encrypted credential vault, SNMP topology, and multi-network profiles. Scan data stays on the user's machine unless they explicitly export it, enable webhooks, or expose the Prometheus endpoint. Subnetlens is built and code-signed by HELIOSOFT LTD and is available as a free version with an optional $79 one-time Pro license.

DeviceShelf
DeviceShelf maps your local network and keeps the map on your own machine. One scan lists every device that answers: vendor, hostname, operating system, device type. It also shows which ports are open and what that means for your security.
It sweeps every adapter at once, identifies devices from MAC OUI, DNS, mDNS/Bonjour, NetBIOS, TTL and DHCP fingerprints, enumerates open TCP and UDP ports with service detection, and writes a prioritised security report: exposed Telnet, RDP, ADB, Docker API or Redis, default credentials, weak TLS and known-CVE hints, each with a fix and a risk score from 0 to 100. In the background it watches who joins and leaves, with uptime, latency and live bandwidth per device.
No account, no telemetry, no cloud sync. Scan results stay on the computer that produced them, and the optional AI assistant runs on your own API key or a local model. One licence covers desktop, mobile and the round-the-clock server edition.

Bopup Scanner
This freeware network scanner displays active computers with logged user names (NetBIOS), MAC and IP addresses. Bopup Scanner also recognizes and shows HTTP (Web) servers running on remote computers (TCP ports 80, 8080), quickly detects online computers, allows to browse shared resources of a remote computer and save results to a text file. Advanced users can enter IP range to scan, change a timeout to resolve a remote host and run the program from a command line interface. Bopup Scanner is a fully portable software. It requires no any setup and installation on a destination computer and can be easily copied to a USB flash drive to move to another PC. The program can be executed with the command line paramaters in order to specify pre-defined options, such as IP range to scan (start and end IP addresses), a path of the file where to save results. So the scanner can be used in batch files as a tool for an automated monitoring.
