Obelinf vs SpatiumDDI

Obelinf combines IP address management, device inventory, data center infrastructure management, network topology, rack management, cable tracking, VLAN/VRF management and infrastructure audit history. Its IPAM tools cover hierarchical subnets, VRF models, VLAN mapping, address status, reservations and live utilization. Interactive diagrams provide site-aware topology views and cable-path tracing; rack tools show elevations, U-position tracking, reservations and utilization across a fleet. A REST API and scoped, revocable keys support automation, while an MCP endpoint lets compatible assistants query and update records. The maker says create, update and delete actions are logged with user, timestamp, context and field-level changes. The free Personal plan allows up to 30 devices, four racks, five subnets, 100 IP addresses, 25 cables and 10 VLANs; VMs and clusters require a paid plan. Personal is free, Teams is $99 a month, and Scale is $299 a month. Paid plans have a 14-day trial that requires a credit card.

SpatiumDDI is a free, self-hosted control plane for DNS, DHCP, and IP address management. Its IPAM organizes hierarchical spaces, blocks, and subnets for IPv4 and IPv6. The control plane manages BIND9, PowerDNS, or Technitium DNS and Kea DHCP configurations, and lists agentless drivers for Cloudflare, Route 53, Azure DNS, Google Cloud DNS, DigitalOcean, Hetzner, Linode, and Vultr. Existing Windows DNS and DHCP servers can connect through RFC 2136 and WinRM without software on domain controllers. Every UI action is exposed through a REST API, with Terraform and Ansible named as clients. Group-based RBAC and LDAP, OIDC, SAML, RADIUS, and TACACS+ are supported. Data stays in PostgreSQL on your infrastructure, with no telemetry or account-data collection stated. Docker Compose and Kubernetes with Helm are supported deployments.
