iVentoy vs OPSI

iVentoy is a PXE/HTTPBoot server for booting and installing operating systems on multiple machines over a network. It runs on Windows and Linux, with Linux server builds for x86_64 and ARM64. The maker lists more than 110 supported operating system types, including Windows, WinPE, Linux, Unix, and VMware. Client boot modes include x86 Legacy BIOS and IA32, x86_64, ARM64, and LoongArch64 UEFI. iVentoy boots ISO files directly without extracting them and retains their native boot menu style. It can install different operating systems on multiple clients simultaneously, filter clients by MAC address or architecture, and assign unattended installation scripts to ISO files. Its HTTP server can serve files inside ISOs without unpacking them. The server includes DHCP and can also use third-party DHCP servers, but DHCP Proxy is not supported. Secure Boot is supported, though client Secure Boot currently works only on x86_64. The Free Edition costs nothing, has no usage time limit, and allows up to 20 clients with no commercial use. Pro costs $49, paid once.

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.
