Use, change and sell it, including inside a closed product. Keep the copyright notice.
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
ORY’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.
