OCS Inventory NG

OCS Inventory NG is open-source asset management software for inventorying devices and supporting software deployment. Agents gather information from client computers, and a management server organizes the results in a web administration console. For network discovery, IP discovery and SNMP scans can find hardware even when it has no OCS agent. Administrators can upload packages for agents to retrieve over HTTP or HTTPS, then review deployment status and statistics. Plugins can extend what agents collect and how the server stores and displays data or controls tasks. A CVE Search feature checks fleet inventory against the CVE-Miter register to flag machines exposed to software vulnerabilities. The software offers connections to ITSM-NG, GLPI, CMDBuild, and iTop through a REST API web service. The free plan is free and includes community support, plugins, and unlimited agents. OCS Cloud is €250 a month. The maker describes version 3.0.0-rc2 as a release candidate for testing, not production deployment.

OCS Inventory NG combines endpoint inventory, agentless network discovery, deployment, and vulnerability exposure checks. The free option includes unlimited agents, while cloud hosting and support are paid offerings.

OCS Inventory NG suits organizations that need a centralized view of device and software inventories, network hardware discovery, or remote package deployment. It is also relevant to teams that use the listed ITSM integrations or want to monitor software vulnerability exposure across a fleet.

Overview

OCS Inventory NG is open-source software for tracking computers and network devices and managing software deployment. It suits IT teams that can run an inventory server and want discovery and deployment in the same system. Its unlimited-agent free plan makes it a strong option for self-managed fleets, while hosted service and expanded support require payment.

Key features

Inventory and discovery

Agents collect hardware and software information from client computers, and a management server brings those results together in a web administration console. IP discovery and SNMP scans can also find network hardware without an OCS agent. That combination is useful for teams that need to account for both managed endpoints and other devices on their networks.

Hardware, software, network asset, and agentless discovery are supported. The publisher lists Windows, Linux, BSD, Sun Solaris, IBM AIX, HP-UX, MacOS X, and Android among supported systems. The broader platform list also includes iOS, API, web, and self-hosted; that range is attractive for mixed environments, though it does not establish identical support across every platform.

Deployment and extensibility

Administrators can upload packages for agents to retrieve over HTTP or HTTPS, with deployment status and statistics available in the console. The publisher says remote deployment is used on fleets exceeding 150,000 machines, making scale a stated strength for organizations managing large installations.

Plugins can add to agent data collection and extend server-side storage, administration displays, and task control. A REST API web service, available since version 2.4, connects OCS Inventory with ITSM-NG, GLPI, CMDBuild, and iTop. These options give IT teams ways to fit the system into existing workflows rather than treating inventory as a standalone list.

Exposure checks and communications

CVE Search compares fleet inventory with the CVE-Miter register to identify machines running software associated with vulnerabilities. This can help teams spot exposure from the software they have inventoried, but it is a focused inventory cross-reference rather than a reason to treat OCS as a general security platform.

Agents and the management server communicate over HTTP or HTTPS, sending XML data compressed with zlib. OCS uses a hybrid deployment model, so it can suit teams comfortable operating infrastructure as well as those considering hosted service.

Pricing

OCS Free costs nothing, billed 0 € / month. It includes the complete software, community support, plugins, and unlimited agents. This is the clearest fit for organizations able to host and administer the system themselves; the trade-off is community rather than unlimited support.

OCS Cloud costs €250 a month, billed 250 € / month. It includes SaaS hosting, unlimited support, and updates. Teams that want the service hosted and support included can avoid running the server themselves, but pay a recurring monthly fee instead of using the free self-managed option.

OCS Pro (up to 10,000 agents) costs €92,500 a year, billed 0,9 € / agent + 2500 € / an. It is on-premise and includes up to 10,000 agents, unlimited support, advanced documentation, and project expertise. This is aimed at larger organizations that need those support and project services; the 10,000-agent ceiling matters when sizing a fleet.

OCS Pro (more than 10,000 agents) has custom pricing. It is an on-premise option for fleets above 10,000 agents with unlimited support. The free plan's unlimited agents are a notable contrast, but it does not include the Pro plan's specified support, documentation, and project expertise.

The free package includes community support. A best-effort one-hour support ticket is also offered for €120, a limited paid option for teams needing a discrete support response rather than a broader support package.

Platforms

OCS Inventory is listed for Android, iOS, Linux, macOS, Windows, web, API, and self-hosted use. The supported-systems list also names BSD, Sun Solaris, IBM AIX, and HP-UX. The breadth is useful for organizations with varied environments, while the hybrid model means teams should consider their hosting and administration capacity.

Who it's for

OCS Inventory is a good fit for IT departments that want device inventory, agentless network discovery, and remote deployment together, especially when unlimited agents on a free self-managed plan are valuable. Its plugin and API options also suit teams integrating inventory with service-management or configuration-management tools.

It is less compelling for teams that want a hosted service without a monthly charge, or that require unlimited support on the free tier. The maker announced OCS Inventory 3.0.0-rc2 on August 26, 2026, and describes that release candidate as for testing, not production deployment; production teams should not treat that candidate as a production release.

Pros and cons

• Pros: The free plan includes unlimited agents, so there is no stated agent cap for self-managed users.
• Pros: Agent-based collection and IP/SNMP discovery cover both client computers and hardware without agents.
• Pros: Deployment status, plugins, API integrations, and CVE cross-referencing bring useful fleet-management work into one system.
• Cons: Free users receive community support; unlimited support is included in paid Cloud and Pro plans.
• Cons: Hosted OCS Cloud costs €250 a month, so the free option is not a hosted alternative.
• Cons: The published Pro tier for up to 10,000 agents is priced at €92,500 a year, and its agent limit may not fit larger fleets.

Alternatives

GLPI is worth considering for teams that prefer a freemium option with a free trial and a Public Cloud plan priced at €19 a month per IT agent, from one billed agent; that plan includes 5 GB disk and a 20 MB maximum attachment size.

InvGate Asset Management is a paid alternative with a Starter plan at $1,499 a year for 500 IP devices, suited to buyers looking for a defined device allowance and paid plan.

Lansweeper offers a freemium option with a free trial that continues free for up to 100 assets and unlimited user seats, which may fit smaller inventories.

IT Asset Tool has a free Basic plan capped at 35 assets, making it an option for a small inventory rather than OCS's unlimited-agent free tier.

LOGINventory provides a no-time-limit free plan for up to 20 devices, which may suit a very small environment.

Open-AudIT offers a free plan with unlimited devices and community support, so it is another option for teams prioritizing a free, self-managed inventory.

rxInventory is a freemium alternative for readers to compare with OCS Inventory.

CloudQuery has a free plan with a 1M-row limitation, cloud asset inventory in your database, an MCP server, and more than 50 sources; it may suit teams whose priority is cloud asset inventory and source breadth.

Verdict

Choose OCS Inventory NG if your IT team wants broad device discovery and deployment with no agent cap and can manage a self-hosted system. Its combination of agent inventory, agentless scans, integrations, and exposure checks is the main reason to choose it. Look elsewhere if hosted service or stronger support is essential but the Cloud or Pro pricing does not fit.
