OCS Inventory NG review
A broad open-source inventory platform for hardware, software, and network discovery.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OCS Inventory NG is open-source IT asset inventory software for organizations that need centralized visibility into computers, servers, software, and network devices. Agents collect hardware and software information and send it to a management server with a web administration console. IP-based discovery, SNMP scanning, and agentless discovery extend coverage to devices that may not run an agent. It suits teams seeking a free inventory foundation with self-hosted, cloud, or supported on-premise deployment options.
Its ecosystem fit is broad. The platform supports web, Windows, macOS, Linux, iOS, Android, API, and self-hosted use. Integrations include GLPI, iTop, CMDBuild, ITSM-NG, and LDAP, while the REST API supports connections to other systems. Remote package deployment and plugin extensions add operational scope beyond inventory collection. These capabilities make OCS Inventory NG a practical fit for environments that need discovery across endpoint and network layers, especially when existing IT service or configuration management tools are part of the workflow.
The plan structure separates free software from hosted and publisher-supported options. OCS Free includes complete software, community support, plugin access, and unlimited agents. OCS Cloud adds SaaS delivery, publisher support, hosting or outsourcing, and included updates. OCS Pro provides publisher-supported on-premise deployment, unlimited support, advanced documentation, and access to project expertise; deployments above 10,000 agents use custom pricing. Choose OCS Inventory NG when open-source flexibility and wide discovery coverage matter. Organizations wanting only a narrowly focused inventory tool, or production deployments centered on the identified 3.0.0-rc2 release, should consider another option.
