    The ones that you build yourself and load with free & open source software. Basically any x86 PC or even ARM SBCs like the Raspberry Pi can work as a router, as long as you have 2 separate network interfaces. There are quite a few FOSS router/firewall operating systems like OpenWRT, dd-wrt, pfSense and OPNSense (my personal favorite). If you don’t want to do this yourself, there are companies like Protectli that offer dedicated pre-built hardware that’s ensured to be compatible with pfSense/OPNSense and comes Coreboot pre-installed.
