It does look great! Looks like the perfect FOSS alternative for Cerberus Anti-Theft.
But is Cloudflare required to use FMD?
So I just use it by authorizing my wife a and kids to use fmd commands, which means I just tell my wife to send me a text with "fmd ring" and it will start ringing until I find and stop it.
Also, it will message my wife and kids if the phone gets below 5%
it is not, OP states in their blog that they use a cloudflare reverse proxy (probably a cloudflare tunnel) to secure the fmd instance, but you can also just not expose it to the web and use a VPN to access it on your home network :)
