OpenIPAM vs SpatiumDDI

OpenIPAM is a free, open-source IP address management and CMDB tool for network and infrastructure inventory. It manages CIDR subnets, IP assignments and reservations, duplicate-IP conflicts, VLANs, IP ranges, and subnet calculations. DHCP tracking covers scopes, leases, reservations, options, and utilization. Its inventory supports 14 host types, hardware lifecycle tracking, locations and racks, maintenance windows, and company records. It can run in a browser with local storage or use an optional Python Flask backend with server-side SQLite for multi-user access. Server mode adds SAML 2.0 single sign-on with Microsoft Entra ID, authenticated routes, and a REST API for entity management, cross-entity search, dashboard statistics, and JSON backup or import. The project describes signed session cookies with an eight-hour lifetime and user-attributed audit entries. CSV host import and JSON backup and restore, including DHCP data, are supported. Browser-mode data stays in the browser; server-mode data is stored in the server-side SQLite file. The plan costs nothing. Current browser support covers Chrome, Firefox, Safari, and Edge, with WebAssembly and ES6+ required.

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.
