Danbyte vs OpenIPAM

Danbyte is an open-source IP address management, data-center infrastructure management and network source-of-truth platform. It tracks IP space, hardware, cabling, power, virtualization, monitoring and automation in one system. For IPAM, it calculates prefix containment, available space and utilization per VRF, and handles VLANs, DHCP ranges, DNS zones and route targets. Its DCIM tools model rack elevations, device faceplates, ports, power and virtual chassis. Network views include cable and fibre tracing, floor plans, circuits, VPN tunnels and wireless SSIDs. Proxmox VE and VMware vCenter imports cover virtual machines and related infrastructure, with drift reconciliation; active checks, SNMP and nmap discovery help maintain an observed layer. Automation options include Ansible and Terraform inventories, Jinja templates, signed webhooks and scoped APIs. Danbyte can run on user hardware, including fully air-gapped deployments, without telemetry or an expiring license. The free, self-hosted offer includes all features without seat licensing. The Linux quick installer bundles Python, Node and dependencies but requires PostgreSQL 15+ and Redis.

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.
