Frequently asked questions about Pandora FMS Open Source

Click to show / hide FAQs

1. What are the differences in updates between Open Source, Free, and ONE versions?

Choosing the right version depends on your needs and technical expertise. The ONE and Free versions offer the most up-to-date features and receive priority bug fixes within hours through our support team. The Open Source version, while completely free with unlimited usage, requires more technical knowledge for installation and updates (which you'll need to apply manually from the GitHub repository).

2. What's the difference between Open Source and the Free version?

Think of the Open Source version as the building block. It offers core functionalities but requires a "do-it-yourself" approach, including installation and updates. You can even modify or extend the code to create your own version. Unlike the Free version, it has no usage limits.

The Free version, on the other hand, provides all the features of the ONE version, but with a limit of 50 agents and 600 modules. It also comes with the benefit of receiving priority bug fixes through support.

3. How can I switch from Free/Open Source to Pro? Will I lose data?

Upgrading to the ONE version is a smooth process, and your existing monitoring data won't be affected. We offer two options: you can leverage our migration assistance service for a hassle-free transition, or follow the easy-to-understand instructions provided by our support team to upgrade on your own.
