CopyleftGPL-3.0
Free to run in-house. Distribute it, or software built on it, and that source must be released under the GPL too.
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 Reaction Commerce’s own README as written. We have not run it, and most projects expect you to set secrets or a database before production use.
docker-compose up -d pnpm run start:dev
