SparrowDNS is a developer-focused DNS platform from SparrowHost Technologies Private Limited, designed to help users manage authoritative DNS for client and parked domains. Its core engine combines native DNS infrastructure with anycast nameservers, aiming to deliver fast global query responses and automatic failover. The platform supports creating DNS zones and managing records through its client portal or REST API, making it suitable for operational workflows and automated deployments.

SparrowDNS also offers on-demand TLS certificate issuance for custom domains using a Caddy reverse proxy, along with real-time synchronization so portal changes are reflected on live DNS services. Developers can generate API keys with permissions scoped to tasks such as reading zones, writing records, or administering an account. Available REST endpoints include listing and adding zones, creating DNS records, and deleting records. By making portal operations accessible through API requests, SparrowDNS enables teams to incorporate domain configuration and DNS management into their pipelines.
