Open Source Statement

graphwiz.ai is built on open-source software, and we are committed to the principles of open source. This page documents what is open and the reasoning behind the technologies we use.

What is open source?

Open source refers to software whose source code is publicly available for inspection, use, modification, and redistribution, under specific open-source licenses. A widely recognized definition is published by the Open Source Initiative at opensource.org/osd.

Our stance

We stand behind the principles of open source — transparency, security, and collaborative development — and adopt open technologies wherever they are the right fit for the job. The entire subject matter of this site (graph-powered AI) is built around open, interoperable systems.

Open source we use

• Next.js & React — the web framework that powers this site
• Neo4j — the graph database at the core of the knowledge graphs we build and document
• vLLM — the serving engine used to run LLMs on self-hosted GPU infrastructure
• Node.js — the runtime for tooling and pipelines
• Git & GitHub — collaboration and version control, with this site's source on GitHub
• Docker & container infrastructure — for reproducible deployment

The source code for substantial parts of this platform is publicly available on the tobias-weiss-ai-xr GitHub organization.

Components with other licenses

Not every component is open source. Some models and services are provided under their own or commercial licenses. We are transparent about these boundaries: where source code is open, it is available; where it is not, that is disclosed. Where a component uses a chosen with a a commercial or other license, we document that choice.
