In their own words
OpenIPAM
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.
Subnetly
Subnetly is a hybrid SaaS DDI platform for DNS, DHCP, IP address management, network discovery, and network visibility. Its dashboard records IP use and ownership, identifies conflicts and orphaned addresses, and can export QBR data. Local agents manage authoritative DNS zones and DHCP scopes, with a SaaS console coordinating records and configurations. Agents scan active network segments using ARP, SNMP, and ICMP to build a hardware asset registry. Subnetly says its AI insights can identify capacity risks and configuration gaps as well as address issues. Deployment options include Docker, Kubernetes/Helm, Windows Server, and a Linux daemon. The company says agents communicate outbound over HTTPS or TLS without open inbound ports or VPN tunnels. REST APIs and monitoring webhooks support third-party automation, though access varies by paid tier. MSP controls cover customer and site separation, technician roles, and audit records. A free plan is available; paid plans start at $49 a month. Starter and Pro include 14-day trials, Business has a 21-day trial, and signup requires no credit card.
