Instead of OPSI
OPSI alternatives
OPSI brings software rollout, operating-system installation, inventory, patching, and configuration under one open-source client management system. It can install Windows and common Linux systems unattended, distribute Windows updates and software packages, and gather hardware details even before an operating system is present. Centralized management across sites and a browser-based interface add flexibility. Community is free for unlimited devices, while Basic is free for up to 30; Professional and Enterprise start at 100 devices and cost €499 and €899 per year respectively.

A different tool may be a closer fit if you need a specific management focus or a different operating model. OPSI’s strongest coverage is Windows, Linux, and macOS, and Basic is limited to one setup per user and excludes support for non-free modules. Consider whether your priority is patch deployment, mobile-device policies, infrastructure configuration, workflow orchestration, or AWS resource state. Also compare platform coverage, deployment model, free-tier limits, and the kind of reporting or integrations each alternative provides.
