YScan

Finds every device on your local network using an ARP sweep, mDNS service browsing, SSDP/UPnP and reverse DNS, then puts them in a live table you can sort and search by IP, name, MAC or manufacturer. Devices that come back unnamed get probed further through reverse DNS and HTTP banners, which is usually enough to identify a Proxmox box, a TrueNAS, a Pi-hole or a UniFi controller by name instead of by address.

Manufacturer names are resolved from the MAC's OUI, so even hardware it cannot name still tells you something. Any device can be port scanned on demand across 29 common ports. There is a oneshot mode that runs a single scan and prints a table or JSON for scripting, and rescans can run continuously in the background at whatever interval you set. Eight themes ship with it and t cycles them live.
