Why Developers Prefer OnlyDNS Over Azure DNS

Managing DNS inside Azure requires navigating enterprise billing agreements, Active Directory app registrations, and slow portal interfaces. OnlyDNS gives you pure, instant DNS control.

Azure DNS Friction

Enterprise complexity: Requires Azure subscription IDs, Resource Groups, and Entra ID (Azure AD) client secrets.
No native dynamic DNS: Lacks standard RFC 2136 TSIG protocol support for container dynamic records.
No AI agent tool integration: Autonomous LLM agents cannot easily manipulate DNS records without custom Azure wrappers.
Per-zone pricing: Costs $0.50/month per zone plus query fees, penalizing development and staging environments.

The OnlyDNS Experience

Instant 30-second setup: Create an account and provision DNS records via clean REST API tokens or web portal.
Native RFC 2136 & TSIG keys: Standard Dynamic DNS for Kubernetes, nsupdate, and cloud-native automation.
Official Model Context Protocol (MCP): Direct agent tool integration for Claude Desktop, Cursor, and LangChain.
Rapid global propagation: Fast sync across 23 global Tier 1 Anycast PoPs (typically 0.2–5s).
