ESP-KVM turns an ESP32-P4 board and an HDMI capture board into an IP-KVM: the screen, keyboard and mouse of another computer in your browser, from the BIOS up. Boot it from an ISO, keep a dashcam that saves the minutes before a crash, reach it from anywhere over Tailscale or WireGuard. It is one firmware image with no OS: nothing to maintain, safe to power off, and a failed update rolls itself back. Flash it from the browser, no toolchain.
