What a business may do with it
Not identifiedNOASSERTION
GitHub could not match this licence to a standard one. It may be custom or source-available; read the repository’s LICENSE file before relying on it.
This describes the licence family GitHub identified, not legal advice about this project. The repository’s own LICENSE file is what binds you.
Run it yourself
Flax Engine’s README does not show a docker run, docker compose up or helm install in a code block, so this page will not guess one. It may be a desktop app, a library, or documented on its website.
