# Licensing and commercial use

CS2 Server Manager is licensed under the [PolyForm Noncommercial License 1.0.0](LICENSE). The source is public and free to use, change and share for non-commercial purposes. It is not "open source" in the OSI sense.

The rule is simple: **if you earn money from it, you need a license.** If nobody earns money from your events, it's free.

## Free, no permission needed

- Personal use, hobby projects, learning and research, under the license's personal-use terms.
- Tournaments and LAN events where nobody earns money from your events: all entry fees and sponsor money go back into the event, and no organizer, volunteer or helper is paid or takes profit.
- Use by the organizations the license lists: charities, schools and universities, public research, public safety or health and environmental protection organizations, and government bodies. They are free even when they charge entry.
- Changing the code, forking it and sharing your changes, as long as you keep the LICENSE and the `Required Notice` line, and your use stays non-commercial.

## Commercial use needs a license

Examples of commercial use:

- Hosting or running CS2 Server Manager for someone else for money, including managed hosting and "tournaments as a service".
- Selling CS2 Server Manager, a modified version of it, or a product or service built on it.
- Running tournaments or events where the organizer makes a profit.
- Using it inside a business, for example an esports organization, venue or company running events.
- Being paid to set up, install or operate Auto Tournament, CS2 Server Manager or Ready Up for someone else, even for a flat fee, and even when that event is itself free.

Forks and modified versions stay under the same license; they can't be relicensed (for example as MIT) or used commercially without a license.

Not sure whether your use counts as commercial? Ask first.

- Third-party Go modules compiled into csm stay under their own licenses: [THIRD_PARTY_NOTICES.md](THIRD_PARTY_NOTICES.md).
