AdGuard Home is a network-wide software for blocking ads & tracking. After you set it up, it'll cover ALL your home devices, and you don't need any client-side software for that.
It operates as a DNS server that re-routes tracking domains to a "black hole," thus preventing your devices from connecting to those servers. It's based on software we use for our public AdGuard DNS servers -- both share a lot of common code.
Navidrome is a self-hosted, open source music server and streamer. It gives you freedom to listen to your music collection from any browser or mobile device.
