Good fit for Authoritative-only deployments where minimal attack surface and high performance per CPU matter (TLDs, DNS providers).

Weak at No bundled UI; less common in tutorials than BIND/PowerDNS.

In a terminal? npx -y github:SolvoHQ/os-alt-cli cloudflare-dns prints the Cloudflare DNS comparison table including NSD + Knot DNS. how the CLI works →

Replaces these SaaS

  • Cloudflare DNS · Authoritative DNS hosting

    NSD is authoritative-only (smaller attack surface than BIND, which combines authoritative + recursive). Install `nsd` from your distro, write zone files in `/etc/nsd/zones/`, list each zone in `/etc/nsd/nsd.conf` under a `zone:` block. Knot DNS is similar but supports DNS-over-TLS / QUIC for modern privacy hardening. Cloudflare export → BIND-format zone file is consumable by both.
