02 / Licence

Licence and access.

Ghost Observatory is free of charge under a proprietary licence. The documentation is publicly readable. Adapter contracts are plain YAML that you can inspect and edit.

Software: Proprietary, and free of charge. The right to use it comes from a written licence from Ghost Citadel Ltd.
Documentation: Publicly readable.
Adapter contracts: Plain YAML that you can read and change, in a folder of your own.
Sample result: Synthetic data. Download it and open it in any SQLite tool.
Libraries: Third-party libraries stay under their own licences. The Engine vendors none of their code.
In the software: No licence key, no account and no usage meter. Core analysis runs locally; an optional hosted AI endpoint is a separate connection you configure.

03 / Questions

Pricing questions.

Is it open source?

No. The software is proprietary and free of charge. The documentation is open, and the adapter contracts are plain YAML that you can read and change.

What does consulting cost?

Pricing depends on the scope. Tell us your systems and requirements. We identify what the core supports and quote the additional work before implementation.

What is consulting for?

New adapters, integrations, controlled deployments and your choice of AI. Regional variants are scoped around your organisation’s requirements.

Where does my data go?

The Engine and Reader run on your machine. They do not upload process data to Ghost Citadel. You control the result file.

When can I get it?

Ghost Observatory is coming soon. Explore the sample result and Reader views available on this site while development continues.
