Summary

OPSI is an open-source client management system for automating software distribution, operating-system installation, inventory, patch management, and configuration. It can install Windows updates, MSI packages, setup programs, and system packages without interactive steps. It also automates Windows client and server installations and common Linux distributions, including unattended and image-based setups. Inventory collects hardware and software details regularly, including hardware information when a device has no operating system. Administration can be centralized across multiple sites, each with its own depot servers, configurations, and software packages. Directory options include Active Directory, Samba 4, and OpenLDAP; single sign-on supports Microsoft Entra ID and Keycloak through SAML 2.0. OPSI-WebGUI runs in a modern browser without client-side installation. Community is free with unlimited devices and one worker process; Basic is free for up to 30 devices and one setup per user. Professional costs 499.00 EUR per year and requires a minimum purchase of 100 devices.
