What’s the use-case for pihole and unbound together?

Aren’t they both DNS servers?

Pi-hole forwards the requests to another DNS server. Unbound can ask the root servers and go down the DNS chain.

  Guess I’m not following, both still have to request from other DNS servers, so what does unbound add?

    Forwarding: just passes the DNS query to another DNS server (e.g. your ISP’s). Home routers use forwarding to pass DNS queries from your home network’s clients to your ISP’s DNS servers. For example, for foo.example.com, a forwarding DNS server would first check its cache (did it already ask this question before), and if the answer is not in its cache, it would ask its forwarder (your ISP’s DNS server) for the answer, which would respond with either a cached response, or would perform recursion until it figured out the answer.
    
    Recursion: the DNS server receiving the query takes it upon itself to figure out the answer to that query by recursively querying authoritative DNS servers for that domain. For example, for foo.example.com, a recursor would first query the root servers for what DNS servers are responsible for the .com TLD, then it would ask those servers for example.com, then it would query the servers for example.com for foo.example.com, finally getting the answer to the original query.
    
    Copy-pate from here.
    
    Basically, it remove one middle man from the DNS resolving.

    Cool, thanks for the clarification. This is good info to have in here in general.
