# Commercial Licensing

Kiln is open-source software licensed under the [GNU Affero General Public License v3.0](LICENSE) (AGPL-3.0).

## When You Need a Commercial License

The AGPL-3.0 requires that if you modify Kiln or use it as part of a networked service, you must make your complete source code available under the same license. This is great for open-source projects and personal use, but may not work for companies building proprietary products.

**You need a commercial license if:**

- You embed Kiln in a proprietary product or service
- You modify Kiln and don't want to open-source your changes
- You offer Kiln's functionality as part of a hosted/SaaS platform
- Your company's legal or compliance requirements prohibit AGPL

**You do NOT need a commercial license if:**

- You use Kiln as-is for your own printing (personal or business)
- You contribute improvements back to the open-source project
- You're building an open-source project that's also AGPL-3.0 compatible

## Getting a Commercial License

Commercial licenses are available from **Hadron Labs Inc** on a per-organization basis.

Contact **adam@kiln3d.com** with:

- Your company name and size
- How you plan to use Kiln
- Whether you need kiln-pro features as well

We'll work out terms that fit your use case.
