Since the 2017 launch of PiKVM, the IP KVM market has exploded, offering hardware that lets you control a machine’s keyboard, video and mouse over a network. The author tested almost every consumer‑grade device, from high‑end units with PoE and 5G backup to sub‑$50 models. These boxes fill a gap where software remotes consume resources or fail if the host is locked or powered down.

The flagship PiKVM line starts at roughly $270 for the Mini and climbs to about $400 for the v4 Plus, which packs a Raspberry Pi CM4, 1080p @ 60 fps HDMI passthrough, two‑way audio and optional 4G/5G PCIe cards. All firmware sits under a GPLv3 license, allowing DIY builds that save money while supporting the open‑source project that seeded the whole category.

At the low end, the Sipeed NanoKVM Cube sells for $69 and gained notoriety after a FBI investigation linked it to espionage attempts, thanks to its tiny microphone and obscure RISC‑V board. While the device works, its firmware lagged behind open‑source releases, raising trust concerns. The roundup underscores that IP KVMs deliver remote BIOS access but demand careful network isolation and regular updates.
