Promocean is open core. The embeddable client packages (@promocean/sdk,
@promocean/widgets, @promocean/contracts, @promocean/cli,
@promocean/config) are MIT-licensed: use them in any codebase, commercial or
not, with no further obligations. See LICENSING.md for the map.
The platform itself (the runtime API, the CMS, the demo app, and the core/adapter packages behind them) is licensed GPL-3.0-only. You can self-host it in production for free, forever, provided you comply with the GPL's terms, including making the source of any modifications you distribute available under the same license.
A commercial (non-GPL) license for the platform is available if you want to:
- embed or white-label the Promocean platform inside a proprietary product you distribute to customers;
- offer Promocean itself (or a derivative) as a hosted service without GPL source obligations;
- satisfy an internal policy that disallows GPL software in your deployment, even where the GPL's obligations would not actually bind you.
Simply using a self-hosted Promocean to serve your own app (calling its API from your proprietary frontend/backend) does not require a commercial license: the GPL applies to distributing the platform, and the MIT client packages are what live in your codebase.
Open a licensing inquiry on GitHub (fine to keep details high-level in public; we'll move to email for specifics). Include roughly: what you're deploying, whether it's distributed or hosted, and your expected scale. Enterprise plans on Promocean Cloud include a commercial license.
