Technitium DNS Server

Technitium DNS Server is a self-hosted DNS management platform that helps users run private, secure, and high-performance DNS infrastructure across home and enterprise networks. They enable users to host recursive and authoritative DNS servers, block ads and malware at the DNS level, and secure DNS traffic using encrypted protocols, making network management more private and efficient. The platform supports DNS-over-HTTPS, DNS-over-TLS, DNS-over-QUIC, and advanced DNS caching, allowing users to improve security, privacy, and browsing performance across connected devices.

They provide advanced capabilities like network-wide ad blocking, DNSSEC validation, built-in DHCP services, clustering, role-based access control, and API-based automation, enabling organizations and advanced users to manage DNS infrastructure with flexibility and control. Users can leverage Docker deployment, OpenID Connect SSO, query logging, encrypted forwarders, DNS Apps, geolocation-based routing, and wildcard domain support, while also benefiting from cross-platform support for Windows, Linux, macOS, and Raspberry Pi. With open-source architecture, multi-user management, and enterprise-grade DNS functionality, they support developers, privacy-focused users, and IT teams managing secure DNS environments.

And the best part? They offer free and open-source access under the GNU GPLv3 license.
