OPSI vs Pushlink

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.

Pushlink is an agent-based service for keeping private Android applications updated without a third-party update process. Administrators upload encrypted APK files; Pushlink says traffic uses SSL and hosted files are not published or installed by others. Devices can enroll through QR codes, an API and CLI, or revocable safe links. After uploading an APK, administrators can make it current and choose status-bar, popup, or background updates. The service reports online and offline installations, update counts, device status, last contact, and device ID, with optional model, IMEI, SIM, or IP details. Exception alerts arrive by email, with Java stack traces and the last 100 Android LogCat lines captured. A web API handles APK uploads outside the administration panel and provides device metadata. Official integrations include.NET and Cordova; community plugins exist for Flutter, React Native, and Gradle but are not supported by Pushlink. The Free plan costs nothing for up to five installations. Monthly per-installation billing is available with volume discounts; price is calculated from installation count.
