Licensing
Greenlight uses a source-available model under the Business Source License 1.1 (BUSL-1.1) — not an OSI-approved open source license for the current community edition.
This page is informational and not legal advice. Review the repository
LICENSE before commercial reliance.

What you may not do
- Offer Greenlight (or a substantially similar product) to third parties as a commercial hosted, managed, or subscription service that competes with the Licensor’s paid hosted offerings

Who may sell subscriptions
| Party | Sell Greenlight as a hosted subscription |

Change Date
Under BUSL-1.1, each version eventually converts to Apache License 2.0. For this
distribution the Change Date is four years from first public publication, and no
earlier than 2030-07-25. See repository NOTICE.
Enterprise proprietary code does not automatically become Apache-2.0.
FAQ
Is this open source?

Can I run it at work for our own agents?
Yes, for internal / self-hosted use under the Additional Use Grant.
Can I start a competing “Greenlight as a Service”?
No, not under BUSL-1.1 while Additional Use Grant restrictions apply.
