Canonical Landscape vs OPSI

Canonical Landscape manages and monitors Ubuntu deployments, including desktops, servers, cloud instances and IoT devices. It can install, update and remove software, apply automated update and security-patch policies, and configure users and groups. For monitoring, it can alert on updates, chart temperature, disk, memory and system-load trends, show running processes and collect custom metrics. It also supports patch-compliance reporting, role-based access control, audit logging, APT repository mirroring and custom package management. Landscape can run as multi-tenant SaaS, as a Canonical-managed single-tenant service, or self-hosted on cloud or on-premises infrastructure, including air-gapped environments. One instance can manage up to 40,000 machines, with larger deployments possible. A scriptable API supports customization and integrations with configuration-management, monitoring and ticketing systems. Self-hosted Landscape and SaaS included with Ubuntu Pro are listed at free. Managed options cost $6,861 a year on supported public-cloud or virtualization environments, or $9,470 a year on bare metal, billed per physical machine. Ubuntu Pro offers a 30-day enterprise trial.

OPSI is an open-source client management system for software distribution, operating-system installation, inventory, patch management, and configuration. It can deploy Windows updates, MSI packages, setup programs, and system packages without interactive installation steps. It also automates installations of Windows client and server systems and common Linux distributions, including unattended and image-based setups.

Regular inventory collects hardware and software details, including hardware information from devices without an operating system. Administration can be centralized across multiple sites, each with its own depot servers, configurations, and software packages. Directory integrations support Active Directory, Samba 4, and OpenLDAP; single sign-on extensions support 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 a year and requires a minimum purchase of 100 devices; Enterprise costs €899 a year with the same minimum. Enterprise Cloud costs €1,199 a year, starting at 100 devices.
