Obelinf

Obelinf is a web and API service for connecting IPAM, equipment records, racks, cabling and network relationships. It fits network engineers, infrastructure teams and IT administrators who need one model for physical and virtual sites, from a homelab to a multi-site estate. Its integrated views are compelling, but the free tier is tightly capped and paid plans start at $99 per month.

Overview

Obelinf brings infrastructure inventory, data-center management, address management, topology, rack planning, cable and circuit records, VLAN/VRF data, and change history into one service. That is useful when an IP address, device, rack position and connection must be understood together instead of maintained in separate documents. It runs through the web and an API, and the maker's free homelab plan does not require self-hosting.

The product covers physical and virtual infrastructure, but virtual machines and clusters require a paid plan. That distinction makes Personal a sensible way to document a small physical environment, not a complete free tier for teams whose inventory is primarily virtual.

Key features

IPAM supports hierarchical subnets, VRF modeling, VLAN mapping, address-status tracking, reservations and live utilization. These controls suit segmented networks where allocation, reservations and remaining capacity matter as much as a list of addresses.

Obelinf generates interactive, site-aware topology diagrams from infrastructure documentation and can trace cable paths. Rack management adds interactive elevations, true U-position tracking, reservations and fleet-wide utilization views. Alongside device inventory, cable tracking, circuit management and relationship mapping, this makes the service more suitable for physical-infrastructure documentation than an IPAM-only product.

Its audit history records create, update and delete operations with the user, timestamp, context and field-level changes. That gives administrators a precise change trail rather than only a current-state view. A REST API and scoped, revocable API keys support automation and third-party tools. An MCP endpoint lets Claude, Cursor and other MCP-capable assistants query and update records with scoped keys; teams should still govern those write permissions carefully.

Single sign-on through OpenID Connect, together with SSO and RBAC, is available on Scale and above. Personal therefore suits an individual or very small operation, while larger teams need a paid tier for centralized access control.

Pricing

Personal — free, billed $0/mo. One user, one organization, one site and four racks are included, with up to 30 devices, community support, five subnets, 100 IP addresses, 25 cables and 10 VLANs. It is a credible starting point for a homelab or compact site, but the caps arrive quickly in a production inventory, and VMs and clusters are excluded.

Teams — $99 a month, billed $99/mo. This raises capacity to 10 team members, three organizations, 10 sites and 200 devices, with priority support. It is the practical entry point for a small infrastructure group managing several locations; it does not include the Scale tier's SSO and RBAC.

Scale — $299 a month, billed $299/mo. Up to 50 team members, 10 organizations, 100 sites and 600 devices are covered, with SSO and RBAC plus priority support. This is aimed at distributed teams that need governance as well as more capacity.

Enterprise — custom pricing. Unlimited team members, organizations, sites and devices are paired with dedicated support. It is the only plan without stated numeric ceilings, so larger deployments must obtain a custom quote.

Paid plans include a 14-day trial of the selected tier and require a credit card to start. Stripe processes payments; Obelinf says it does not store card details on its servers, and Stripe is PCI Level 1 certified.

Platforms

Obelinf is delivered through a web interface and API. The no-self-hosting Personal option lowers setup overhead for homelabs and small teams, while API access supports integrations and automation.

Who it's for

Choose Obelinf when network and infrastructure staff need IPAM, racks, topology, cabling and audit records in the same system, especially across multiple sites. Personal is best for an individual documenting a modest environment; Teams fits a small shared operation; Scale is the stronger match when site count, device volume or identity controls are central requirements. It is less suitable if you need virtual-machine tracking on a free plan or prefer a self-managed, open-source deployment.

Pros and cons

Pros

• Connected infrastructure model: IPAM, inventory, topology, racks, cables, circuits and relationships can be managed together.
• Useful operational views: site-aware diagrams, cable-path tracing and true rack U-position tracking address day-to-day documentation needs.
• Automation and accountability: REST access, revocable scoped keys, MCP integration and field-level audit history support controlled workflows.
• Clear growth tiers: device, site, organization and user limits make the jump from Personal to Teams or Scale easy to assess.

Cons

• Personal is narrowly bounded: 30 devices, four racks, five subnets, 100 IP addresses, 25 cables and 10 VLANs leave little room for a growing network.
• Virtual inventory costs extra: VMs and clusters are not included on the free plan.
• Governance starts at Scale: SSO and RBAC are unavailable on Teams.
• Paid entry is substantial: Teams starts at $99 per month, and Enterprise pricing is custom.

Verdict

Obelinf is a strong choice for teams that want IPAM, physical infrastructure documentation, topology and auditable automation in one hosted system. Start with Personal for a small homelab, but expect to move to Teams or Scale as device, site and access-control needs grow. Look elsewhere if self-hosting, extensive virtual inventory on a free plan, or a lower recurring cost is the priority.
