RedundantDNS and the alternatives

Multi-provider DNS as code, secondary DNS from a managed vendor, or a service that keeps the zone in sync for you. Honest comparisons, dated.

RedundantDNS vs octoDNS

octoDNS syncs a YAML zone to many DNS providers from your CI. RedundantDNS runs the same diff and apply as a service, with a dashboard, probes and alerts.
RedundantDNS vs DNSControl

DNSControl pushes a JavaScript-defined zone to several providers from CI. RedundantDNS keeps the zone in sync continuously, with verification, probes and alerts.
Multi-provider DNS vs secondary DNS

Secondary DNS copies a zone from a primary by zone transfer. Multi-provider DNS writes the zone to each provider through its API. Differences, limits and prices.

Put your zone on two providers

Start with a 30-day trial: one zone on two providers you already have, no card. Plans from $9 a month after that.
