Our verdict on OPSI
OPSI is an open-source client-management system from uib GmbH for organizations administering Windows, Linux, and macOS computers. Its scope covers automated software distribution and patch management, operating-system installation, configuration of systems and programs, hardware and software inventory, and centralized administration across multiple locations. The product uses a hybrid deployment model, with self-hosted on-premise software and a separate hosted cloud option. It is best suited to teams that want centralized endpoint administration with a free community entry point and broad Windows and Linux management capabilities.
Pricing is structured across five plans. Community provides unlimited devices and core features, while Basic is limited to 30 devices. Professional is listed at €4.99 per device per year with annual billing, Enterprise at €8.99 per device per year, and Enterprise Cloud at €11.99 per device per year. The published paid-plan pricing is shown for a minimum of 100 devices. That structure gives smaller deployments a free route, while organizations with larger environments can choose progressively higher paid tiers or the cloud option. Buyers should compare the plan scope carefully, especially if they need more than the Basic limit or want hosted delivery.
OPSI also fits environments with established directory and monitoring systems. Integrations include Active Directory, Samba 4, and OpenLDAP extensions for directory connectivity, plus Nagios-compatible monitoring such as Icinga. WAN/VPN caching supports remote-client software delivery, and operating-system installation includes Secure Boot support and WIM image capture for Windows reinstallation. The product is a strong choice for organizations seeking open-source, multi-location management across Windows and Linux, with macOS support included in its platform coverage. It is less suitable for teams seeking an AI-focused tool or a simple desktop-only utility.
