PiKVM.cn is a PiKVM community and hardware kit site for Chinese-speaking users. Its core focus is building open-source, cost-effective IP-KVM solutions based on hardware such as Raspberry Pi and domestic Linux development boards. It is not traditional remote desktop software; instead, it enables hardware-level out-of-band management through HDMI capture, USB keyboard/mouse emulation, and power control. This means the target machine can still be operated even when no operating system is installed, the system has crashed, or it is in BIOS/UEFI.
In terms of features, it covers remote KVM, ATX power on/off, WOL network wake-up, virtual USB flash drive/CD-ROM system reinstallation, H.264/MJPEG/WebRTC video streaming, VNC, Webterm, 2FA, GPIO/USB relays, and one-to-many control. No software needs to be installed on the controlled device, making it suitable for Windows, mac, and Linux servers, as well as Arm/x86 industrial PCs. The project is based on Linux/Armbian and PiKVM, uses the GPLv3 open-source license, and emphasizes that there is no closed-source software, root access is open, and HTTP API and API calling capabilities are provided.
Its business model is mainly free open-source software plus one-time hardware kit purchases. The S805 series focuses on low-cost operations and maintenance, priced at around 148-245 yuan, and is suitable for server rooms, industrial control, temporary office setups, and similar scenarios. However, it does not support audio synchronization, and its WebRTC capabilities are limited. The full-featured R1 version costs around 378-536 yuan and supports higher frame rates, H.264 hardware encoding, and WebRTC audio/video synchronization, making it better suited for remote work, audiovisual use, design, and gaming. Overseas PiKVM V4 series products are significantly more expensive, and the page also notes that imports may be affected by taxes and shipping costs.
Its advantages are that it is open source and auditable, requires no software installation on the controlled machine, can operate at the BIOS level, and offers Chinese documentation covering networking, audio/video, peripherals, advanced usage, and APIs. Availability through Taobao and Xianyu also lowers the barrier for users in China to obtain the hardware. The downsides are that remote public Internet access usually still requires users to configure port forwarding, Tailscale, Frp, OpenP2P, or Cloudflared themselves; different kits vary significantly in HDMI loop-out, power-on methods, frame rate, audio, and encoding, which makes product selection harder for non-technical users. Technical support mainly comes from the WeChat official account and community, and no enterprise-grade SLA description was found.
It is suitable for IT operations teams, industrial control/medical/energy/transportation equipment maintenance personnel, and users who want a low-cost alternative to TeamViewer, ToDesk, Sunlogin, or traditional IP-KVM. The website and purchasing channels are aimed at the domestic Chinese market, so access should be direct from within China. However, if third-party networking services such as Tailscale or Cloudflared are used, actual availability will still depend on the network environment.
