DNSimple

DNSimple is a domain registrar and DNS host founded in 2010 on the premise that domain management should be easy. The platform is API-first, with a deliberately plain interface at a time when competing providers buried essential features under configuration options.

Several capabilities arrived early. Two-factor authentication shipped in 2012, ahead of most DNS providers. ALIAS records were created to solve the CNAME-at-apex problem. Educational material such as "How DNS Works" and "How HTTPS Works" explains the protocol through mascot characters named Trusty (the authoritative name server) and Resolver (the recursive resolver).

Automation and integration carry most of the weight. The Domain Control Plane connects on-premise and third-party systems through secure APIs, giving enterprises one interface for domains spread across multiple registrars and providers. Bulk DNS record editing is available through the API for Enterprise customers, so teams can manage hundreds of domains with the same Infrastructure as Code practices used for the rest of their stack.

DNSimple has been an ICANN accredited registrar since 2013, handling registration, transfers, and renewals across hundreds of top-level domains. Built around that core are SSL certificate purchasing, DNSSEC support with automated key rotation through CDS/CDNSKEY records, vanity name servers for white-label DNS hosting, and integrated DNS providers that sync records to services such as Azure DNS and Route 53.

The Enterprise feature set targets how larger companies actually manage domains. Microsoft Entra SSO handles team access. Activity tracking provides full audit history for compliance. Zone verification blocks DNS takeover by requiring ownership verification when a zone is added. CAA records let organizations control which certificate authorities can issue certificates for their domains.

DNSimple manages DNS for over 40,000 domains on a global Anycast network. The customer base has widened from individual developers to enterprises managing thousands of domains.
