License overview
The rzfz.ai Stack — the integrated open-source stack for local AI infrastructure — bundles curated open-source components. This page lists the license of each module, with a link to the respective license text.
The components developed by razzfazz.ai GmbH itself (marked „First-party") are licensed under the Business Source License 1.1 (BUSL-1.1, source-available). All other modules are third-party open-source projects under the licenses shown. For components under copyleft licenses (e.g. GPL, AGPL) we provide the corresponding source code on request, in line with the license terms.
Language models: The Stack can run various open AI models (LLMs). These are subject to the license terms of the respective model providers (e.g. Apache-2.0, or model-specific terms such as the Gemma Terms of Use) and are not listed individually here — the specific models shipped are named in each offer.
