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
Docker Compose, quoted from GrowthBook’s own README as written. We have not run it, and most projects expect you to set secrets or a database before production use.
git clone https://github.com/growthbook/growthbook.git cd growthbook docker compose up -d
