NSD + Knot DNS vs PowerDNS
Self-host pick — both replace Cloudflare DNS (Authoritative DNS hosting).
Both NSD + Knot DNS and PowerDNS self-host as a replacement for Cloudflare DNS (Authoritative DNS hosting). Pick NSD + Knot DNS if you want a BSD-licensed codebase (BSD-3-Clause); pick PowerDNS for GPL (GPL-2.0). Both run in roughly the same cost bracket — $5/mo vps minimum vs $5-10/mo per vps; run 2-3 vpss in geographically separated regions for redundancy.

Good fit for
NSD + Knot DNS
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.
PowerDNS
Teams that want a battle-tested, RFC-compliant authoritative DNS with a clean web admin and SQL-backed records.
Weak at:Anycast story — bring your own (BGP + multiple POPs) or accept regional latency; Cloudflare's free anycast is impossible to match cheaply.
In a terminal? npx -y github:SolvoHQ/os-alt-cli cloudflare-dns prints Cloudflare DNS's self-host options including both —
