Commercial & OEM Licensing
Build tcpcat into your product — without the copyleft
1tcpcat is dual-licensed
tcpcat's public version is released under the GNU Affero General Public License v3.0 (AGPL-3.0). You can use, study, modify, and self-host it freely. But the AGPL is copyleft: if you distribute tcpcat, or offer it to others over a network, you must release the complete corresponding source of your product under the AGPL too.
The commercial (OEM) license lifts that obligation, so you can embed tcpcat in a proprietary product or hosted service without open-sourcing your own code.
2Which one do you need?
Free under AGPL-3.0
Personal use, study, and research. A company running tcpcat on its own or its clients' authorized networks. Any project you're happy to release under the AGPL.
Needs a commercial license
Embedding tcpcat in a product, appliance, container image, or VM you sell. Offering it as a hosted/managed service without publishing your source. Reselling or bundling it in a paid product.
3What the OEM license grants
- Incorporate, bundle, and embed tcpcat (source or binary) into your commercial product.
- Distribute it in binary form as part of that product to your end-users.
- Release from the AGPL's copyleft obligations — no requirement to open-source your product.
The full terms are in the repository's COMMERCIAL-LICENSE.md.
