Spec score 8.9 #3 of 26 in IT Asset Discovery Software

What it is

OCS Inventory NG is open-source asset management software that scans and inventories devices and supports software deployment. Agents gather information from client computers, while a management server collects results for a web administration console. IP discovery and SNMP scans can identify network hardware, including devices without an OCS agent. Administrators can upload packages for agents to retrieve over HTTP or HTTPS, then view deployment status and statistics.

A REST API web service supports integrations with ITSM-NG, GLPI, CMDBuild and iTop. Plugins can extend data collection, server storage, administration display and task control. CVE Search compares fleet inventory with the CVE-Miter register to identify machines exposed to software vulnerabilities. The free package includes community support, plugins and unlimited agents. OCS Cloud costs €250 a month and includes SaaS hosting, support and updates. OCS Pro for up to 10,000 agents is listed at 0.9 € per agent plus 2500 € per year; larger deployments have custom pricing.

OCS Inventory NG in depth

Read the full write-up

OCS Inventory NG is open-source software for collecting device inventories, discovering network hardware and deploying packages. It suits IT teams that can run an inventory server and want discovery and deployment together. Its unlimited-agent free plan is a strong starting point; hosted service and paid support cost extra.

Overview

Agents collect information from client computers, and a management server brings those results into a web administration console. IP discovery and SNMP scans add a way to identify hardware without an OCS agent, making OCS useful for teams managing both enrolled endpoints and other network equipment.

OCS Inventory dates to 2001. FactorFX identifies itself as the editor and says it provides integration and support, with locations in Rennes and Granville, France. The deployment model is hybrid. Agent-server traffic uses HTTP or HTTPS, with XML data compressed using zlib.

Key features

Inventory and network discovery

The agent-based model gives administrators a central view of client hardware and software, while IP discovery and SNMP scans can extend discovery to network devices that lack an agent. Hardware, software, network asset and agentless discovery are supported. That combination is useful when a fleet includes unmanaged network hardware, though agent-based collection remains the route for client inventory.

Deployment and extensibility

Administrators can upload packages for agents to retrieve over HTTP or HTTPS, then review deployment status and statistics. This puts software distribution alongside inventory in the same administration system. The publisher says remote deployment is used on fleets exceeding 150,000 machines; that scale claim is relevant to large estates, but does not replace checking operational fit for a particular environment.

Plugins can add agent data collection and extend server-side storage, administration display and task control. A REST API web service, available since version 2.4, supports compatibility with ITSM-NG, GLPI, CMDBuild and iTop. The CVE Search feature compares fleet inventory with the CVE-Miter register to identify machines exposed to software vulnerabilities.

Release status

OCS Inventory 3.0.0-rc2 was announced on August 26, 2026 as a release candidate for testing, not production deployment. Organizations choosing a release should distinguish that candidate from a production-ready version.

Pricing

OCS Free costs nothing (billed 0 € / month). It includes the complete software, community support, plugins and unlimited agents. It is the clearest fit for teams able to rely on community support and operate the software themselves.

OCS Cloud costs €250 a month (billed 250 € / month) and includes SaaS hosting, unlimited support and updates. It trades the free plan's self-operated model for hosted service and support, at a recurring monthly price.

OCS Pro (up to 10,000 agents) costs €92,500 a year (billed 0,9 € / agent + 2500 € / an). It is on-premise, capped at 10,000 agents, and includes unlimited support, advanced documentation and project expertise. The agent ceiling and annual pricing make it a better fit for organizations seeking paid assistance and on-premise operation within that limit than for smaller teams content with community support.

OCS Pro (more than 10,000 agents) has custom pricing. It is on-premise, supports more than 10,000 agents and includes unlimited support. Teams above the smaller Pro tier's ceiling should compare a custom quote with Cloud and Free rather than assume a per-agent price.

The free package includes community support; FactorFX also offers a best-effort one-hour support ticket for €120. That is a narrower support option than the unlimited support included with Cloud and Pro.

Platforms

The main site lists Windows, Linux, BSD, Sun Solaris, IBM AIX, HP-UX, MacOS X and Android support. The platform range also includes iOS, API, self-hosted and web. This breadth can suit mixed environments, while the specific supported-systems list is the more concrete guide for endpoint operating systems.

Who it's for

OCS Inventory is a good match for IT teams that want centralized hardware and software inventory, agentless network discovery and package deployment in one system, especially when unlimited agents on the free plan matter. Teams that need SaaS hosting can choose Cloud; organizations requiring paid on-premise support can consider Pro. It is less suitable for teams that need production deployment of the announced 3.0.0-rc2 candidate or expect unlimited support on the free tier.

Pros and cons

Pro: Unlimited agents on OCS Free let organizations inventory large fleets without a per-agent cap on that plan.

Pro: IP discovery and SNMP scans can find network hardware without agents, complementing endpoint collection.

Pro: Package deployment includes status and statistics, and the publisher cites use on fleets exceeding 150,000 machines.

Pro: Plugins and REST API compatibility with four named ITSM and configuration-management products provide extension and integration routes.

Con: Free support is community-based; the one-hour ticket is best-effort and costs €120.

Con: Cloud costs €250 a month, while the paid on-premise Pro tier has an annual price and a 10,000-agent cap.

Con: The 3.0.0-rc2 release is explicitly for testing, not production deployment.

Alternatives

Compare IT Asset Discovery Software if you want to survey the category before choosing.

Lansweeper is a freemium alternative with a free trial; its free continuation is capped at 100 assets and allows unlimited user seats.

LOGINventory offers a no-time-limit free tier for up to 20 devices, making it a choice to consider for a small device inventory.

CloudQuery has a free tier with a 1M-row limitation, cloud asset inventory in your database, an MCP server and more than 50 sources.

Open-AudIT offers unlimited devices and community support on its free plan, another option for teams prioritizing a free inventory tier.

runZero has a free Community Edition capped at 100 assets, one organization, 10 recurring tasks and 30 days of data retention.

GLPI is another freemium option; its Public Cloud plan starts at €19 a month per IT agent, from one billed agent.

rxInventory is a freemium inventory alternative from Rubinox GmbH.

Komiser is a free alternative with a cloud option.

Verdict

Choose OCS Inventory NG if you want agent-based inventory, agentless network discovery and deployment in one system, and can work within community support or pay for hosting and support. The unlimited-agent free tier is its strongest draw. Look elsewhere if you need a different support model, or do not want to operate an inventory system and the Cloud plan's monthly cost does not fit.

Verdict

OCS Inventory NG combines agent-based inventory with agentless network discovery and deployment tools. Compare the free, cloud and Pro terms carefully, and avoid treating the announced release candidate as production-ready.
