Show HN: Whosthere: A LAN discovery tool with a modern TUI, written in Go
Summary
Whosthere is a local area network discovery tool with a modern Go-based terminal UI (TUI) that performs unprivileged, concurrent scans using mDNS and SSDP, and augments results by triggering ARP resolution to identify devices on the LAN. It provides device enrichment via OUI lookups, an optional port scanner, and a daemon mode with a simple HTTP API, with installation options via Homebrew, Go install, or building from source. The project emphasizes safe, user-space network discovery for admins, with configurable themes, logging, and documentation, under an Apache-2.0 license.
