Open DHCP Server vs SagaOS Kea Pilot

Open DHCP Server is free, open-source software that provides Dynamic Host Configuration Protocol service on Linux and self-hosted, on-premises deployments. It assigns addresses through static hosts and dynamic DHCP ranges, supporting up to 125 ranges on one server. Multiple zones can run on a single server, with BOOTP and relay-agent support. DHCP options may be set globally, for a range, or for an individual client, using string, IP, hexadecimal-string, or byte-array values without defining option types. Ranges can be filtered by MAC ranges, vendor options, and user options. Replicated fail-safe operation supports continuity, while lease status appears on an auto-refreshing HTML page. The project describes low CPU use, small executable size, and very low memory requirements. It is released under the GNU General Public License, with a GPL-2.0 repository license. The project says it suits experts and small or home deployments, including people without DHCP protocol knowledge.

SagaOS Kea Pilot is a web management platform for Kea DHCP, BIND9 DNS, and Dynamic DNS, aimed at ISP and enterprise network operations. It manages DHCPv4 and DHCPv6 subnets, address pools, host reservations, leases, options, and Kea high availability. For DNS, it handles BIND9 zones and records, RFC2136 dynamic updates, and synchronization with DHCP lease events. A live health dashboard, WebSocket updates, service status tracking, performance metrics, audit logs, and analytics support operational monitoring. The platform also lists multi-tenant data isolation and granular role-based access control, with REST endpoints for DHCP and DNS operations. Configuration tools cover backup, restore, versioning, and rollback. Deployment is documented for Linux and Docker, with Ubuntu 20.04+, CentOS 8+, RHEL 8+, and Debian 11+ listed. Minimum requirements are 2 CPU cores, 4 GB RAM, and 20 GB SSD; BIND9 is optional in the minimal installation. The software is MIT licensed and free. The README documents admin/admin as the initial login and says it must be changed for production.
