Resources
Licensing, Enterprise documentation and support paths around the rzfz.ai Stack. Source code and the wiki are above under Open source.
The rzfz.ai Stack's community edition is open source and free to use — no contract, with community support via GitHub.
The rzfz.ai subscription is a license, not a service: it grants your company the right to operate the current, patched version commercially, including releases and access to the gated Enterprise documentation.
The software update service, standard support and trainings are standalone services and not part of the subscription — you book them separately, as needed.
